The period of a pendulum may be decreased by

• Increasing the mass of the bob
• moving the equilibrium point
• decreasing the mass of the bob

In any system in SHM, the restoring force acting on the mass in the system is proportional to

• the displacement
• the length of the pendulum
• the mass
• the frequency

Which of the following is not an example of SHM?

• A simple pendulum
• A vibrating spring
