If Leela is standing on the ground and throws a ball straight up into the air, what will happen to the ball's direction of movement when it reaches its highest point?
Provide a very brief response.
The ball that Leela throws will momentarily stop moving upward when it reaches its highest point. Gravity, which is a force that pulls objects toward the center of the Earth, will then cause the ball to reverse its direction and begin to fall back towards the ground. The ball's upward movement slows down due to gravity until it stops completely at its peak, and then gravity pulls it back down, so the ball's direction of movement changes from up to down at the highest point.
