Blake is the pitcher on his middle school baseball team. Which statement best describes the relationship between the potential and kinetic energy of the baseball when Blake pitches it to the catcher? (you can assume the ball is traveling in a straight path)
a
The potential energy increases and kinetic energy stays the same.
b
The potential energy decreases and kinetic energy increases.
c
The potential energy decreases and kinetic energy decreases.
d
The potential energy stays the same and kinetic energy decreases.

Option (b) The potential energy decreases and kinetic energy increases, best describes the relationship between the potential and kinetic energy of the baseball when Blake pitches it to the catcher.
When Blake pitches the baseball, he exerts a force on the ball, causing the ball to move. As the ball moves, its potential energy decreases because its height from the ground reduces. This decrease in potential energy is converted into kinetic energy of the ball's motion. Thus, the kinetic energy of the baseball increases as its potential energy decreases.
