when a ball is thrown up into the air, its motion undergoes changes. what are these changes? Explain

If a ball is thrown straight up into the air, then on its way up the ball will move upward in a straight line and then descend once the velocity of the ball becomes zero. The speed of the ball with decrease on the way up until it hits zero and it will then fall back down.

Explanation:

When you project an object upward and release it at its initial velocity, it is moving in the opposite direction of the force of gravity ... The object slows down as it moves upward until it reaches a maximum height, at which time the velocity is zero. Then the velocity increases as the object falls toward the ground.
