Objective: To see if Newton's first Law force require to change speed in direction of a moving object.
Hypothesis: It would be greater if it take the force of speed. As a result of the cart it would take more force to change speed or direction of a moving object.
Materials:
-Hall’s Cart200
-gram mass
-Spring
-scale
-String
Procedure:
1. Use the same setup from experiment
2. Start moving at a slow speed by pulling on the string scale.
3. Then quickly pull harder to accelerate the speed of the speed. Repeat 4-5 times while reading the scale.
4. Start rolling slowly by pulling on the spring scale and then pull the scale in a wide arc to change the direction of the cart. Repeat 4-5 times.
5. Record the maximum force for both.
Data: Trial Start Finish
1.) .5n 1n2.
2.) .5n 5n3.
3.) .5n 2n4.
4.).5n 2n5.
5.).5n 1.5n
Conclusion: My hypothesis was correct. I see that when objects with less force and are small move it has a greater chance of going with the force. It had move of a force feild so it was easier to tell.
Real World: We ca apply this in our everyday life when we leave small object around when there a greater force then it.

Experiment
Objective: To see if an object in motion stay in motion without be forced upon an external force.
Hypothesis: The mass in the hall's cart will not fall out. It will stay in becasue there is no force to make it fall out.
Materials:
-cardboard
-wooden ramp
-cart-100g of mass
Procedure: First place the wooden ramp on the floor. Then tape a piece of cardboard over the hole of the cart. Then put 100g mass on top of the cardboard. Push the cart so that it collides with the edge of the wooden ramp. Do this at least 4 to 5 times.
Data:
1.Pulling the cart by the string.
2.Gently forcing to move toward the edge of the ramp.
3.The cart hit the edge of the ramp and it fell off.
Conclusion: My hypothesis is incorrect. I thought that the mass in the cart will weigh the cart down. Around all I learned that althrough something look like it would be in your favor it does not always come out like that.
Real World: I think that we can apply this in our everyday lifes by looking and taking guesses and then seeing our results of things. For example if we are moving something with an object on top of it then we know it has a good change of fall it we do not carry it out right.

Forces/Newton's Law of Motion
Experiment 2
Objective: Is to apply Newton's Law toward this project. Newton's law describes the connection between the casue of a change in an object velocity and the resulting displacement.
Hypothesis: I believe that the cart will not roll due to the weight and the wheel will be stable.
Materials:
-200 grams
- Cart
- String
-Spring Scale
Procedure:
Tie the string to the cart then the scale.
Next you will tug the the cart that is connected to the scale.
Repeat this step 4 more times.
Data:
Step 1- .70n and 75g
Step 2- .30n and 30g
Step 3- 1n and 100g
Conclusion: My thoughts toward this came out to be right. I took the time out to apply the weight in the cart and then came up with it will not move.World Applying: I think that we can use this if we are building a car. A car is something that we use everyday and this would be a good procedure.

Forces/Newton's Law of Motion:
Experiment 1
Objective: The objects at rest remains at rest unless acted upon an external forces.
Hypothesis: I believe that the car will land on the table due to the wheel and the roll back.
Materials Used:
1.)A Cart
2.) 2 by 1
3.) Ruler
Produres:
1.) Set wood on to the table along with the cart.
2.) Measure 8 inch away from the table to measure how far the wood is where the wood belong.
3.) Place the cart on the wood and then pull the wood out fromt he cart.
4.) Repeat this step over about 4 more times.
Data:
Trail 1-Stayed on the table.
Trail 2-Satyed on the table.
Trail 3- Fell off the table.
Trail 4- Stayed on the table.
Trail 5- Stayed on the table.
Conclusion: The cart did what I said what will happen 80% of the time. When I did the third trail it fell because the measurements where a little off or the cart was to far from the table.
