Question 8

A toy consists of a small mass suspended vertically from a stretchable elastic cord. The mass is pulled down to an extension point D D\,D and released from rest. It then oscillates vertically between point D D\,D and a highest point UUU.

Assuming there is no air resistance, which of the following groups contains all the forms of energy that alternately increase and decrease during these oscillations?

A

Gravitational potential energy, kinetic energy, and elastic potential energy

B

Gravitational potential energy and kinetic energy only

C

Elastic potential energy and kinetic energy only

D

Internal energy, gravitational potential energy, and kinetic energy
