Problem
Consider the following experiments:
In experiment 1, a student uses a spring to launch two bouncy balls with different masses. In each test, the spring is pulled back the same distance. The student records how far each ball travels.
In experiment 2, a student throws a baseball as hard as they can and records the speed using a speed radar. Then, the student throws the ball more softly and records the speed again.
Which experiment is the better test of how mass affects an object’s motion?
