Detailed explanation-1: -A ball rolling down a hill has both Kinetic and potential energy. Kinetic energy is due to motion. So if the ball is rolling down it has kinetic energy. Potential energy is the stored energy which is waiting to be used.

Detailed explanation-2: -So when you roll a ball down a ramp, it has the most potential energy when it is at the top, and this potential energy is converted to both translational and rotational kinetic energy as it rolls down.

Detailed explanation-3: -As the skier begins the descent down the hill, potential energy is lost and kinetic energy (i.e., energy of motion) is gained.

Detailed explanation-4: -A body rolling down a hill possesses both kinetic energy and potential energy. At every point, it has some height which means it has potential energy and as it is moving, it also has kinetic energy.

Detailed explanation-5: -Kinetic energy is the type of energy an object has because of its motion.
