Physics

When a ball is thrown upward, the gravitational potential energy is being increased.

Gravitational potential energy is directly related to an object's height in a gravitational field. When the ball is thrown upward, it gains height, which increases its gravitational potential energy relative to the ground.

Option A, Kinetic energy

Initially, when the ball is thrown upward, it has kinetic energy because it is in motion. As the ball moves upward, its velocity decreases due to the gravitational force acting in the opposite direction of its motion. So, the kinetic energy of the ball is decreasing as it moves upward.

Option B, Elastic potential energy
