Velocity Experiment- Pierre Fermat

 Velocity Experiment- Pierre Fermat

 

 

Hypothesis

On the wooden track, I think the marble will go the fastest almost at the bottom of the first hill.  I think this because the ball is speeding up because it is going down the hill. 

 

Materials and Methods

1. Mini Wooden Roller Coaster

2. Giant Triangle

3. Really High Pole

4. Four Marbles

5. Photo Gates

   These are numbers we put the clamps  on. 5 to 10, 40 to 50, 80 to 90, 120 to 125, 60 to 65, and 20 to 30. Thats where our group put the clamps on to see how fast it would go.   

 

 

Data Table (Results)

 The ball ended up going really fast at the bottom of the hill. I think this because thats when it goes fast when it goes down because all the gravity is pushing down.

Discussion

 What we are doing is using a 2 hill wooden roller coaster. We wanted to see how fast it would go per number. It goes Fast at the bottom of both the hills. We used a marble for this experiment.  The fastest was at the end of the coaster. It is at the end. They are all at the end of the coaster.

They are all in common because they stop at the end.
