● g is the acceleration due to gravity

Q. State the changes in energy types when a ball is thrown upward.

Ans - When a ball is at ground level, the potential energy is zero. When it is thrown upward, it moves due to kinetic energy present in the ball by virtue of its motion. As it reaches its maximum height, the kinetic energy is converted to potential energy. As the ball comes down, the potential energy is again converted to kinetic energy.
