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
• shortening the length of pendulum

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

Position at which the body would come to rest if it were to lose all of its energy refers to

• equilibrium position

• maximum displacement / amplitude

• periodic position

• good position

The number of cycles or oscillation made in one second is defined as

• time taken

• period

• frequency

• amplitude
