Final answer:
Observing the motion of a bouncing basketball with a partner, one can identify vertical motion due to gravity and horizontal motion when the partner moves forward. Switching roles aids in understanding the ball's behavior from different perspectives.
Step-by-step explanation:
When observing the motion of a bouncing basketball, you'll note that it includes both linear and vertical components. As your partner bounces the ball while standing in place (Procedure Step 1), the ball moves vertically up and down due to the force of gravity acting upon it reversing its direction with each contact to the ground.
During Step 3, as your partner walks forward with the ball, the motion becomes a combination of horizontal and vertical movements. The horizontal movement is due to the forward motion of your partner, and the vertical component remains due to gravity.
As you switch places with your partner and repeat the steps (Step 4), it helps solidify your understanding of how the bouncing ball behaves when viewed from different perspectives while in motion.
