Write a hypothesis about the effect of the angle of the track on the acceleration of the cart. Use the "if . . . then . . . because . . .” format and be sure to answer the lesson question: "How does an object's position and velocity change as the object accelerates?”

Sample Response: If the angle of the track increases, then the acceleration of the cart increases because a greater track angle increases the cart's velocity.

Explanation:

because.

if they have a finite resultant

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
