At its highest point, a ball has potential energy due to its position in the gravitational field. The ball has the maximum potential energy at this point as it is furthest away from the Earth's center. As it falls back down, this potential energy is converted into kinetic energy.
At the peak of the trajectory the potential energy will be at it's maximum and the vertical component (perpendicular to the earth) will be zero, ie if the ball was thrown straight up from the ground, it will start off with no potential energy and high kinetic energy. As it moves upward, the force of gravity will act on it and it will slow, thus the KE will decrease. At the same time it is gaining altitude, so the PE will increase. A the peak the KE is 0 and the PE is maximized and the ball is motionless. Then the ball will fall towards the earth and its KE will increase as it gains speed and its PE will decrease as it loses altitude until it hits the ground with the same amount of KE it started with, but moving in the opposite direction.
-- A ball on a shelf has gravitational potential energy with respect to the floor. -- A ball in motion has kinetic energy. -- A ball of fire has heat energy. -- A ball of trinitrotoluene has chemical energy. -- A ball of charged pith has static electric energy. -- A ball of U235 has nuclear energy.
When a cricket ball is projected vertically upward, the acceleration acting on the ball is gravitational acceleration directed downward. This causes the ball to slow down until it reaches the highest point of its trajectory, then it accelerates back downward due to gravity.
When a ball is dropped, it has gravitational potential energy that is converted to kinetic energy as it falls due to gravity. This kinetic energy increases as the ball gains speed during the fall.
The ball has potential energy just before it is released, which is due to its height above the ground. This potential energy can be converted into kinetic energy as the ball falls and gains speed.

Moving objects have kinetic energy.
Yes, a golf ball on the grass has potential energy due to its position in the Earth's gravitational field. When the ball is raised to a certain height, it gains potential energy which can be converted into kinetic energy when it is in motion.

When you pull a bowling ball back, you create potential energy, specifically gravitational potential energy, as you elevate the ball against the force of gravity. This energy is stored in the ball due to its position. When you release the ball, this potential energy is converted into kinetic energy as the ball moves forward towards the pins.
