How does Newton's Laws apply to the physical world?

Problem: How does the speed of the toy car effect the distance the wooden block moves?

Hypothesis: I think that the speed of the toy car WILL effect the distance the block moves.

Experiment: Materials

1. one toy car
2. a inclined plane
3. tape
4. one small wooden block
5. a yard stick

                 Procedure  

1. Gather all materials
2. Put the toy carat the top of the ramp
3. Put the wood block at the bottom of the ramp
4. After you have put the toy car and wood block where is should be, push the car down the ramp towards the wood block 
5. Now by using the ruler/yrd.stick, measure from where the wood block at the bottom of the ramp to where the block is now.
6. Next take the ramp and move it so it is steeper then it was to increase the speed the car goes down the ramp.  
7. Next put the car at the top of the ramp, and the wooden block at the bottom again.
8. Keep doing that for about 2-3 more times.

Variables:       CV-The car stayes the same.

                         IV-The stempness of the ramp changes.

                         DV-How far the little block moves after the car hit its.
                         Contol-The car with different speeds. 

Conclustions:  For this experiment i was trying to find out if the speed of the toy car would effect the distance of the wooden block. When i tried the experiment out, the speed did effect the distance of the wooden block.
