Simple harmonic motion
Simple harmonic motion When a body repeats its motion after regular time intervals we say that it is in harmonic motion or periodic motion . The time interval after which the motion is repeated is called the time period. If a body moves to and fro on the same path, it is said to perform oscillation . Simple harmonic motion (SHM) is a special type of oscillation on a straight line , the acceleration of the particle oscillates on a straight line, the acceleration of the particle is always directed towards a fixed point on the line , the acceleration of the particle is always directed towards a fixed point on the line and its magnitude is proportional to the displacement of the particle from the center of oscillation
