Question 14

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?

A

Gravitational potential energy increases, elastic potential energy decreases, and kinetic energy first increases then decreases.

B

Gravitational potential energy increases, elastic potential energy increases, and kinetic energy first decreases then increases.

C

Gravitational potential energy decreases, elastic potential energy increases, and kinetic energy first increases then decreases.

D

Gravitational potential energy decreases, elastic potential energy decreases, and kinetic energy first decreases then increases.
