Question

the graph shows the height of a ball as it bounces. what does each decreasing portion of the graph represent?
bouncing a ball
height
0 time
a. the ball is falling back toward the ground. c. the ball is touching the ground at its lowest
point.
b. the ball has briefly touched the ground and is d. the ball has reached its maximum height of
beginning to rise again. the first bounce.
please select the best answer from the choices provided

Explanation:

In a graph of a ball's height over time as it bounces, a decreasing portion of the graph (where height decreases as time increases) represents the ball's motion when it is moving downwards. When a ball falls back toward the ground, its height relative to the ground reduces as time passes, which matches the description of a decreasing portion of the height - time graph. Option b describes an increasing portion (as the ball rises, height increases with time), option c would be a point (not a portion of the graph), and option d is a peak (a maximum point, not a decreasing portion).

Answer:

a. The ball is falling back toward the ground.
