Simple Hormonic Motion:
Simple Hormonic Motion (SHM) is to and fro oscillatory motion in which acceleration of the body is directly proportional to the displacement of the body from the mean position and is always directed towards the mean position .
Features Of SHM:
i. A body excuting SHM always vibrates about fixed position .
ii. Its acceleration is always directed towards mean position .
iii. Its velocity is Maximum at the mean position and zero at extreme positions.
