How can a stationary metals sphere have kinetic energy, the energy of motion?

Answer 1

A stationary metal sphere can have kinetic energy if it was initially in motion and then came to a stop. When the sphere was moving, it had kinetic energy due to its motion. Even though the sphere is now stationary, it still possesses kinetic energy because of its potential to move again. This kinetic energy is known as potential kinetic energy or stored kinetic energy, and it is the energy that an object possesses due to its position or condition, rather than its actual motion.
