Exp.7
Hypthesis- The rod would shoot out and the cart would not move that much.
1st Try= The cart moved backwards and the rod shot to the front.
2nd Try=The cart moved backwards and the rod shot to the front.
3rd Try=The cart moved backwards and the rod shot to the front.
External force for rod and cart.
No, ,y hypothesis was not correct because the cart moved when I predicted it was not going to move
Objective: To find out if Newton's third law is true.
Hypothesis: The rod will shoot out but the cart won't move that much.
Trial 1- Cart move backwards the rod shoot out.
Trial 2- Cart move backward rod shoot out.
Trial 3- Cart move backward rod shoot out.
1. Rod went upward and the cart went backward.
2. External force for rod & cart.
3. No our hypothesis was not correct.
Hypothesis
For my Hypothesis i think that the rod will shoot off in the oppisite direction, based of of the weight and force of the rod.
The first try the car didnt even move and the rod went striaaght
The second try the rod some how forced the cart to move in the oppisite direction of the rod
The third try the cart moved to the left and the rod went to the right.
My hypothesis was some what correct. One of my test matched my hypothesis
Objective- For every action there is a reaction.
Hypothesis- I Predict when we we pull back on the sling that the rod will fly forward and the cart will move back.Proving Newtons third law that states for every action there is an equal and opposite reaction.
Materials-
Rod
Rubber band
Halls Cart
Procedure- We attached the rubber band to the halls cart and put the Rod inside the rubber band to make a sling shot.
1. The rod went forward and the cart slid back a little.
2.The Rod and the cart both went back.
3.The Rod went forward and the cart moved back.
Conclusion- The Rod moved Forward almost every time we shot it.I believe the force was an equal force reacting to an equal force.My Hypothesis was correct because the rod flew forward and cart slid back proving my hypothesis and Newton's Third law.
Hypothesis: The rod will shoot out but the cart won't move that much.
Trial 1- Cart move backwards the rod shoot out.
Trial 2- Cart move backward rod shoot out.
Trial 3- Cart move backward rod shoot out.
1. Rod went upward and the cart went backward.
2. External force for rod & cart.
3. No our hypothesis was not correct.
Objective:To find out if Newton's Third Law is true.
Hypothesis: I predict that the rod really isn't going to go far and the cart would not move.
Materials: Rod, Rubber Band, and Hall Cart.
Procedures:
1. Find and open area on smooth floor.
2. Attach one end of the rubber band to the hole in the front of the cart with a piece of string or a paper clip.Hook one end of the end of the rod into the other end of the cart.
3. Pull the steel rod in the "sling shot" until there is good tension on the rubber band. Then hold the art rod in place with one hand.
4. Release both the cart and rod at the same time as you let go. Repeat several times, stretching the rubber band the same amount each time.
Data:
Trial 1: Rod flew to the right & cart move left.
Trial 2:Repeated Trial 1
Trial 3: The opposite of Trial 1
Conclusion: The rod had move to the right. I believe the force was an equal force reacting to an equal force. The cart move to the left.My hypothesis was incorrect.
Problem Statement: When two things are attached to each other and are are being pulled back in the same direction, will they be launched in the same direction or will they be launched in the opposite direction?
Objective: The objective of this lab is to determine whether or not two attached objects will be launched in the same direction or in opposite directions according to Newton's third law of motion.
Hypothesis: I predicted that the cart and the steel rod will go in different directions when I released them, following Newton's third law of motion.
Materials: For this experiment, I used a table, a rubber band, a paper clip,, a steel rod(about 12 inches in length), and a cart.
Procedure:
1. Find an open area on a smooth surface (preferably a table).
2. Attach one end of the rubber band to the hole in the front of the cart with a paper clip.
3. Pull the steel rod back in the rubber band(creating a "slingshot" effect) until there is good tension on the rubber band.
4. Hold the cart and the rubber band and the rod in place with one hand.
5. Release both the cart and the rod at the same time.
6. Repeat several times and record in your note book.
Data:
Trial 1: The rod flew in one direction(to the right) and the cart flew in the opposite direction(to the left).
Trial 2: The cart and the rod repeated trial 1.
Trial 3: The cart flew in one direction(to the right) and the rod flew in the opposite direction(to the left) basically doing the opposite of trial 1 and 2.
Conclusion: My hypothesis was correct. I predicted that the cart and the rod would fly in the opposite direction and follow Newton's third law of motion: for every action, their is an equal and an opposite reaction. When the cart was released, it flew to the right and an external force(my hand) was acting upon it. The same applies to the steel rod.
In my opinion, this experiment was easy compared to the other experiments. All of the previous experiments were a tad bit more complicated than this final experiment. I learned a little more about Newton's third law of motion and I learned how to develop an experiment testing this law.
Hypothesis: The rod will shoot out but the cart won't move that much.
Trial 1- Cart move backwards the rod shoot out.
Trial 2- Cart move backward rod shoot out.
Trial 3- Cart move backward rod shoot out.
1. Rod went upward and the cart went backward.
2. External force for rod & cart.
3. No our hypothesis was not correct.
Materials-
Rod
Rubber band
Halls Cart
Procedure:
1. Find an open area on a smooth surface (preferably a table).
2. Attach one end of the rubber band to the hole in the front of the cart with a paper clip.
3. Pull the steel rod back in the rubber band(creating a "slingshot" effect) until there is good tension on the rubber band.

Objective:For every action there is a reaction.
Hypothesis: I predict that when the sling is pulled back, then the rod will move/fly forward while the cart moves back.
Materials:
Rod
Rubber band
Halls Cart
Procedure:
1- The rod went forward and the cart slid back a little.
2-The Rod and the cart both went back.
3-The Rod went forward and the cart moved back.
Conclusion-Our hypothesis was true because the rod did move forward each time. I do believe that the force was an equal force reacting to an equal force.
Hypothesis- I predict that the rod will go very far possibly hitting someone in the process.
Materials- In this Lab we used A Rod, A Rubber Band, and A Hall's Cart.
Data-
The first try the car didnt even move and the rod went straight an hit one of my partners.
The second try the rod when sideways forced the cart to move in the oppisite direction.
The third try the cart moved to the left and the rod went to the right.
My hypothesis was correct each time we we did the procedure the rod took off at a very fast paste caused it to shoot out and hit people.
Objective: The objective of this lab is to determine whether or not two attached objects will be launched in the same direction or in opposite directions according to Newton's third law of motion.
Hypothesis:
Procedure:
1. Find an open area on a smooth surface.
2. Attach one end of the rubber band to the hole in the front of the cart with a paper clip.
3. Pull the steel rod back in the rubber band until there is good tension on the rubber band (creating a "slingshot" effect).
4. Hold the cart and the rubber band and the rod in place with one hand.
5. Release both the cart and the rod at the same time.
6. Repeat several times and record it.
Data:
Trial 1: The rod flew in one direction(to the right) and the cart flew in the opposite direction(to the left).
Trial 2: The cart and the rod repeated trial 1.
Trial 3: The cart flew in one direction(to the right) and the rod flew in the opposite direction(to the left) basically doing the opposite of trial 1 and 2.
Conclusion: My hypothesis was correct. I predicted that the cart and the rod would fly in the opposite direction and follow Newton's third law of motion: for every action, their is an equal and an opposite reaction. When the cart was released, it flew to the right and an external force(my hand) was acting upon it. The same applies to the steel rod.

Objective: The objective of this lab is to determine whether or not two attached objects will be launched in the same direction or in opposite directions according to Newton's third law of motion.
Hypothesis: I think that the rod will shoot far but it wont stay straight when it shoots and the cart will move backwards when the rod gets shot.
Materials: Rod, Rubber Band, and a Hall Cart.
Procedure:
1. Find an open area on a smooth surface.
2. Attach one end of the rubber band to the hole in the front of the cart with a paper clip.
3. Pull the steel rod back in the rubber band until there is good tension on the rubber band (creating a "slingshot" effect).
4. Hold the cart and the rubber band and the rod in place with one hand.
5. Release both the cart and the rod at the same time.
6. Repeated doing this 3 times and record it.
Data:
The first try the car didn’t even move and the rod went straight an hit one of my partners.
The second try the rod when sideways forced the cart to move in the opposite direction.
The third try the cart moved to the left and the rod went to the right.
Conclusion:
My hypothesis was right and wrong, because the first time we shot the rod it went straight and hit Thomas in his leg and the cart didn’t even move. But then the next couple of times we did it the rod shot sideways and the cart move in the opposite direction that the rod went.
