A ball is dropped and it hits the floor at a point A. It rebounds upward to a point B. While moving from A to B its?
kinetic energy is increasing
potential energy is increasing
potential energy is decreasing
kinetic energy remains constant
解释
The Kinetic Energy of a body is energy possessed by a body as a result of its motion.
Hence, while in motion the kinetic energy of a body changes into potential energy as it rebounds from the floor
