Simple Harmonic Motion (S. H. M.)

Edit

Periodic motion:

Any motion which repeats itself in equal intervals of time is defined as periodic motion. It is also defined as harmonic motion.

The constant interval of time after which the motion is repeated is known as time period.

Oscillatory:

The motion of body moves back and forth (to and fro) about a fixed point after regular interval of time is defined as oscillatory.

The fixed point about which the body oscillates is known as mean position.

Some Basic Terms for S. H. M.

Edit

Mean position:

The point at which the restoring force on the particle is zero and potential energy is minimum, is known as its mean position.

Restoring Force:

  • The force acting on the particle which tends to bring the particle towards its mean position, is called restoring force.
  • This force is always directed towards the mean position.

Amplitude:

Amplitude is defined as the maximum displacement of…
