A person throws a ball up into the air, and the ball

Question

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

Answer 1

The kinetic energy of the ball would be the lowest when the ball is at its highest point. At this point, the ball momentarily stops before it starts to fall back down, resulting in the minimum kinetic energy. Kinetic energy is highest when the ball is moving and reaches its lowest value (which is zero) when it is at the highest point. Therefore, the correct answer is:

when the ball is at its highest point.
