Question

a softball player throws a ball into the air and catched it on the way down. ignoring the air resistance that acts on the ball, state the energy conversions that act on the ball?​

Answer 1

Answer:

When the ball is thrown by the softball player, work is done by the player to the ball, making the ball gain kinetic energy which transforms into gravitational potential energy once it reaches its maximum height.

This gravitational potential energy transforms back to kinetic energy as the ball falls down to the softball player's catcher's mitt or hand or the minimum height, and this kinetic energy on the ball means work is done on the player by the ball.

See the illustration below.
