A mass is suspended from a vertical spring and oscillates repeatedly between a high point A A\,A and a low point BBB. Throughout the entire oscillation, the spring remains extended.
As the mass moves upward from the lowest point B B\,B to the highest point AAA, how do the gravitational potential energy, the elastic potential energy, and the kinetic energy of the system change?
Gravitational potential energy increases, elastic potential energy decreases, and kinetic energy first increases then decreases.
Gravitational potential energy increases, elastic potential energy increases, and kinetic energy first decreases then increases.
