SHM

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

What are the two requirements for a simple harmonic oscillator?

• The object vibrates about the equilibrium point and the restoring force is proportional to the displacement

• The object moves left to right and the restoring force is proportional to the displacement

• The object vibrates about the equilibrium and the restoring force is greater than the displacement

• The object moves left to right and the restoring force is greater than the displacement

For a system in simple harmonic motion, which of the following is the number of cycles or vibrations per unit of time?

• amplitude

• period

• frequency

• revolution

A simple harmonic oscillator takes 4.8 s to undergo five complete vibrations. What is the frequency of 1cycle?
