Front 7

As a mass oscillates back and forth on a friction less surface, is the energy being conserved?

Back 7

The energy is being conserved.

Front 8

What force causes the pendulum to move towards equilibrium?

Back 8

Force of Gravity.

Front 9

Describe the motion of the bob as it moves away from equilibrium.
