Question

select the correct answer from each drop - down menu. when you throw a ball upward, its kinetic energy and its potential energy. when the ball reaches maximum height, its kinetic energy is at a

Explanation:

The kinetic energy of an object in vertical - motion is related to its velocity. When a ball is thrown upward, its initial velocity is maximum at the start, so its kinetic energy is maximum. As it moves up, its velocity decreases due to the gravitational force acting against the motion, and the kinetic energy is converted into potential energy. At the maximum height, the velocity of the ball is zero (momentarily), so the kinetic energy is at a minimum. The potential energy is given by $U = mgh$, where $h$ is the height. As the height increases, the potential energy increases. So when the ball reaches the maximum height, its potential energy is at a maximum.

Answer:

When you throw a ball upward, its kinetic energy is at a maximum initially and its potential energy is at a minimum initially. When the ball reaches maximum height, its kinetic energy is at a minimum and its potential energy is at a maximum.
