Question

A person throws a ball up into the air, and the ball falls back toward Earth. At which point would the kinetic energy be the lowest?(1 point) Responses when the ball is at its highest point when the ball is at its highest point when the ball leaves the person’s hand when the ball leaves the person’s hand at a point when the ball is still rising at a point when the ball is still rising at a point before the ball hits the ground

Answer 1

The kinetic energy of the ball is lowest when the ball is at its highest point. At this moment, the ball's velocity is momentarily zero before it starts to fall back down, which means its kinetic energy (which depends on the velocity) is also zero at that instant. Thus, the correct response is:

**When the ball is at its highest point.**
