Problem Statement: Do objects at rest really remain at rest unless acted upon by external forces?
Objective: The purpose of this lab report is to grasp the concept of force and to learn Newton's laws of motion. We will have to complete a series of experiments and labs in order to understand the different components that make up the three laws of motion.
Hypothesis: During this lab, I predict that the ramp will cause the cart to roll along or fall off the ramp and onto the floor, due to the force that was applied when jerking the ramp off of the table.
Procedure:
First, I had to set a wooden plank (the ramp) on a table with about 12'' of the ramp extended over the edge of the tables.
Second, I had to place the cart on the part of the wooden ramp that was on the table.
Third, I stood to one side and quickly jerked the ramp out from underneath the cart.
I had to repeat step three 4 or 5 times and record my observations.
Equations: There were no equations used in this lab.
Data:
Trial 1: The cart did not fall or roll. It just slid backwards onto the table.
Trial 2: The cart repeated trial 1.
Trail 3: The cart slid off of the left side of the ramp and onto the table.
Trial 4: The cart repeated trials 1and 2.
Conclusion: My hypothesis was partially correct. I predicted that the cart would fall off the ramp and onto the floor. Although the cart fell off the ramp, it did not fall onto the floor. The cart did not follow Newton's first law for a body at rest. Displayed by data, the cart did not stay at rest. The car moved with each applied amount of force.
I think that I would change the placement of the ramp. I feel that if I were to have a slanted ramp, the cart would create better results. I also feel that the cart should have been smaller because if it had a smaller mass, the cart would be able to travel farther down the ramp. Nothing went wrong with my experiment or my data. Everything was accurate.
I, somewhat, grasped that concept of Newton's first law of motion. I feel that I should create a lengthier experiment and further develop my research when trying to learn Newton's first law of motion.
There are a numerous ways this lab could be used in practical applications. People that construct cars may use this law to determine whether a car is capable of stopping correctly and remaining at rest.

Experiment 1
• My Hypothesis: I believe that the ramp will make the cart roll off but it will stay on the table. It might just even roll back on the table.
Trials My Observation
1 I observed that the cart stayed on the table. The cart rolled a little forward.
2 “ ‘ ‘ ‘ ‘ ‘ “
3 I observed the cart rolled towards the back. It stayed on the table.
4 It rolled towards the front, and it also stayed on the table
5 “ “ “ “
• Was my Hypothesis correct: Yes, it was correct in some form of way. It did not roll backwards but it did stay on the table.
• Yes it follows Newton’s first law for a body at rest.
State The Problem: Do objects at rest really remain at rest unless acted uopn by external forces.
Objective: The reason for this lab is to find out if the force required to move an object from rest is the different from the force that is required to move an object constantly.
Hypothesis: I predicted that if the ramp is pulled the cart will not flip over or fall, it will move back. It will remain in the same position it was in the beginning.
Materials: While doing this experiment, I used many materials such as a ruler, a cart, wood plank, a 8"(inch)long piece of string, a 200 gram mass used to apply pressure to the cart, and a spring scale.
Procedure: 1.Tie one end of the 8" piece of string to the cart and tie a loop in the free end of the string.
2. Place the 200 grams mass into the cart.
3.Zero the spring scale and attach the hook from the spring scale to the loop of the scale.
4.Tug on the spring scale several times to start the cart.
5.Jerk on the spring scale several times rapidly to the cart moving.
6.Pull the cart across the across the table at a constant speed several times.
7. Recored the data and did it over and over until the experiment was completed.
Data:I made a graph that showed what happened while pulling the ramp from under the cart on the y- axis was the time and on the x-axis was the observations. My data shows all of the trails I did, the amount of grams the cart weighed,and how the cart reacted after being jerked and tugged.
Conclusion: The lab was pretty much easy. I had to learn to use a critical eye when measuring and make sure I was accurate. I learned alot from the experiment like newton's laws and how the force is different when a object's at rest rather than at constant speed.

Experiment 1 and 2
~ My Hypothesis: if the ramp is pulled from under the cart i think it will roll backwards just a little bit
~Trials My Observation
1. rolled froward all five times
2. the cart never rolled off of the table.
~Was my Hypothesis correct: no it was opposite
~Yes it follows Newton’s first law for a body at rest.
~ My Hypothesis: i think the force will stay the same at rest and being pulled.
it will roll backwards just a little bit
~Trials My Observation
1. the grams and newtons changed each time.
Lab Report 1
Objective:
The objective of this lab is to learn Newton’s law of motions.
Hypothesis:
I think if you pull the ramp, the cart will move backwards on the table.
Materials:
1. Wooden ramp
2. Cart
Procedure:
First, I had to set a wooden plank (the ramp) on a table with about 12'' of the ramp extended over the edge of the tables.
Second, I had to place the cart on the part of the wooden ramp that was on the table.
Third, I stood to one side and quickly jerked the ramp out from underneath the cart.
I had to repeat step three 4 or 5 times and record my observations.
Data:
Trial 1 - The cart did not fall or roll. It just slides onto the table Backwards.
Trial 2- The cart did the same thing it did in trial 1.
Trial 3- The cart slides off of the left side of the ramp.
Trial 4- The cart did the same thing it did in trials 1 and 2.
Conclusion:
After we removed the ramp all the cart did was move backward onto the table. My hypothesis was correct, I my hypothesis stated that the cart will move backwards on the table.Only thing is that it didn’t move it slided.
I think that the cart did follow Newton’s first law because his law states that an object at rest tends to stay at rest and an object in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The cart was at rest on the ramp but when you moved the ramp the cart moves.

Experiment 1
Do objects at rest really remain at rest unless acted upon by external foreces?
Objective:The whole reason for this lab report was to learn the Newtons laws of motion and to learn more of force. We had to do an experiment and we had to complete a lab to understand.
Hypothesis:I predict that the cart will move and it will roll over and fall when the ramp is pulled out from under it, and that it would be the same force required.
Procedure:
First, We had to to put the ramp flat on the table,with it being
12" over the egde of the table.We had to measusre it to make sure that it was exactly at 12".
Second,we took the cart and placed it on top on the ramp which was on the table.
Third,Then we had to stand to one side and quickly pull(jerk)the ramp from under the cart.
Fourth,we had to do the same thing 4-5 times.
Data:
Trial 1-The cart didnot roll or move it just stayed the same.
Trial 2-Same as Trial 1.
Trial 3-Same as Trial 2.
Trial 4-Same as Trial 3.
Conclusion:My hypothesis was correct. The newton law stated that "An object at rest remains at rest" was true.Througout the whole lab the cart stayed at at rest.
Objective:Is to determine do objects at rest really remain at rest unless acted upon by external forces.
My hypothesis- my hypothesis is that when the wooden board is moved from under the cart will remain at the same place that it was sitting on the wooden board, only it will roll a bit afterwards.
Trail 1 – yes After the board/ramp was removed from under the cart, it stayed in its place and sort of rolled a bit
Trail 2 –After the board/ramp was removed from under the cart, it stayed in its place and sort of rolled a bit
Trail 3 –After the board/ramp was removed from under the cart, it stayed in its place and sort of rolled a bit
Trail 4 –After the board/ramp was removed from under the cart, it stayed in its place and sort of rolled a bit
My results- my hypothesis was correct! Because i moved the wooden ramp swiftly from under the cart it kinda rolled backward but mostly foward.
My conclusion- As I stated my hypothesis was correct. Newton’s first law states that an object at rest remains at rest and a moving object will continue moving unless force was added to it. So the data I recorded went in perspective of the definition of the first law of motion. What i learned in this lab is that when something is moved really fast from under something the object that is on the top remains at the same place but it may move a bit. What i would change in this lab would be the wooden board to a metal to prevent splinters (thanx ms.karla).And last i would compare this to life situations like a bike because people could use this experiment to see if the bike is capable of stoping and remaining at rest.
State The Problem: Do objects at rest really remain at rest unless acted uopn by external forces.
Objective: The reason for this lab is to find out if the force required to move an object from rest is the different from the force that is required to move an object constantly.
Hypothesis: I predicted that the cart wouldnt really pull put it wouldnt go backwards or flip over
Materials: While doing this experiment, I used many materials such as a ruler, a cart, wood plank, a 8"(inch)long piece of string, a 200 gram mass used to apply pressure to the cart, and a spring scale.
Procedure: 1.Tie one end of the 8" piece of string to the cart and tie a loop in the free end of the string.
2. Place the 200 grams mass into the cart.
3.Zero the spring scale and attach the hook from the spring scale to the loop of the scale.
4.Tug on the spring scale several times to start the cart.
5.Jerk on the spring scale several times rapidly to the cart moving.
6.Pull the cart across the across the table at a constant speed several times.
7. Recored the data and did it over and over until the experiment was completed.
Data:I made a graph that showed what happened while pulling the ramp from under the cart on the y- axis was the time and on the x-axis was the observations. My data shows all of the trails I did, the amount of grams the cart weighed,and how the cart reacted after being jerked and tugged.
Conclusion: My conclusion was that my hypthisis was right and lab help my learn a little bit abbout newtons law
Objectives: The objective for this lab was to address this question “Do objects at rest really remain at rest unless acted upon by external forces?”
Materials: Ramp, Cart, Wood, Table
Hypothesis: I think if you pull the ramp from underneath that the cart will fall onto the floor.
Procedures:
1. Set the wooden ramp on a table with about 12” of the ramp extending over the edge of the tables.
2. Place the Hall’s cart pm is the (art of the ramp that is over the table. The cart at this point is in a state of rest.
3. Standing to one side, quickly jerk the ramp out from underneath the Hall’s cart. Try this 4-5 times. Record your observations.
4. Analyze your results.
Data:
Trial 1: The cart did not fall or roll. It just slides onto the table backwards.
Trial 2: The cart did the same thing it in trial 1.
Trial 3: The cart slide off of the left side of the ramp.
Trial 4: The cart did the same thing it did in trial 1 & 2.
Conclusion: My hypothesis was somewhat correct. I predicted that the cart would fall off the ramp and onto the floor. In addition, the cart fell off the ramp; it did not fall onto the floor. The cart did not follow Newton's first law for a body at rest. Displayed by data, the cart did not stay at rest. The car moved only when applied a certain amount of force.
Ojective:
The purpose of this lab was to determine if the object followed newtons first law for a body at rest.
Hypothesis:
I predicted that when we pulled the ramp from under the cart that the cart would roll backward.
Materials:
WOODEN RAMP
RULER
HALL CART
Procedure:
first me and my group members placed the wooden ramp about 12" on the edge of the table.
Then we jerked the ramp out from underneath the hall cart, we observed and recorded it about five times.
finally we analyzed our results.
Data:
Trial one- the cart rolled back and stopped.
Trial two- the cart rolled back and stopped.
Trial three- The cart rolled back and stopped.
Trial four- The cart rolled back and stopped.
Trial five- The cart rolled back and stopped.
Conclusion:
My hypothesis was correct i predicted that the hall cart would roll back. I was correct in the experiment when we pulled the wooden ramp it rolled back and stopped. This Experiment followed newtons first law. It had no net force which meant that it didn't move, it stayed it's same position.
The Main Problem:Do objects at rest really remain at rest unless acted upon by external forces?
Objective: The main idea of this lab is to learn about the concept of force and also learn about the Newton's law of motion. We had to complete a task of different test for this lab to understand the different laws of motion.
Hypothesis:During my test i predict that the force from me pulling the ramp will cause the cart to fall of the ramp, and move just forward but will not fall onto the floor.
Procedures:
First, We had to set the board of wood on the edge of the table, and the wood had to be 12" off the end of the table.
Next, we had to place our little blue cart on the other end of the wood that was on the table.
Then, one of I had to stand on the opposite side of the board and pull the wooden ramp as quick as possible. [I had to repeat these steps 4 to 5 different times, and jot down my results/observations]
Equations:We did not have to use any type of equations for this type of lab.
Observations:
Test1: The cart moved forward slightly once I pulled the board from be neigh it.
Test2: The cart did not move once I pulled the board from be neigh it.
Test3: The cart did not move once I pulled the board from be neigh it.
Test4: The cart moved forward slightly once I pulled the board from be neigh it.
Conclusion: My Hypothesis was somewhat correct, but at some of the test the cart just stayed still and did not move at all, therefore
I was wrong.
The cart did somewhat follow Newtons law of motion because the cart did not move every time i pulled the board from be neigh the cart.
Maybe if we would have moved the board closer then maybe the cart would have moved every time and then it would not be following the law of motion [Newton's].
Problem: Do objects at rest really remain at rest unless acted upon by external forces?
Objective:The purpose of this lab report is to understand Newton's laws of motion.
Hypothesis: I predict that the cart will simply fall back off the ramp, because we pulled the ramp from underneath the cart.
Procedure:
Step1-place ramp on table,have 12" of the ramp hanging off the edge of the table.
Step2-Place the cart on the half of the ramp that is on the table
Step3-Stand to one side and quickly jerk the ramp from underneath the cart
Repeat the step about four times and record data
Equations: No equations used
Data:
Trial 1-The cart did not roll or fall it slid backwards of the ramp and then did not move.
Trial 2-Same as Trial 1.
Trial 3-Same as Trial 2.
Trial 4-Same as Trial 3.
Conclusion: My hypothesis was correct. The car did slid back and was at rest when it slid backwards of the ramp.
I think that some real world applications would be a car should learn how to stop and be at rest.
I really enjoyed the project it was very hands on. Me and my group members understood the lab and was very excited to do the lab.
I would not change the lab. I thought that it was fine just like it was.
Hypothesis: The cart would move when the board was jerk but will still on the board after.
Material used: Woodern ramp
Ruler
Table
Hall's cart
Procedure: 1. Set the wooden ramp on a table with about 12" of the ramp extending over the edge of the table.
2. Place the Hall's cart pm the art of the ramp that is over the table. The cat at this point is in a state of rest.
3. Standing to one side, quickly jerk the ramp out from underneath the hall's cart. Try this 4-5 times.
4. Analyze your results.
Data: Trail 1: Cart came off but move anlittle bit.
Trail 2: Cart came off but didnt move as much.
Trail 3: Cart came off but didnt move as much.
Trail 4: Cart came off but didnt move as much.
Conclusion:
The cart came off, and hit the table. When it did that the cart move just an bit then came to rest. Our hypothesis was not correct but this experiment did follow Newton's first law for an body at rest.
Experiment 1
Problem- Will an object at rest remain at rest unless moved by an external force.
Objective- The purpose of this lab is to prove if Newtons first law is true.
Hypothesis- I predict that once the ramp is pulled from under the cart, the cart will land in the same spot on the table.Proving that Newtons first law is true,which states that an object at rest will remain at rest or that an object in motion will remain constant in a straight line.
Material-
Wood ramp
Ruler
Cart
Procedure- First I put took the ruler and measured 12 inches and thats how much the wood ,would hand of the table.
Then I put the cart on it and pulled thewould from under it.
Conclusion- When I pulled the ramp from under the cart, it landed on the table in the exact spot it was before,proving that Newtons first law is true.
