Definition of simple harmonic motion
: a harmonic motion of constant amplitude in which the acceleration is proportional and oppositely directed to the displacement of the body from a position of equilibrium : the projection on any diameter of a point in uniform motion around a circle
of simple harmonic motion
THEORY
When an object moves to and fro along a line, the motion is called simple harmonic motion. Have you seen a pendulum? When we swing it, it moves to and fro along the same line. These are called oscillations. Oscillations of a pendulum are an example of simple harmonic motion.
Now, consider there is a spring that is fixed at one end. When there is no force applied to it, it is at its equilibrium position. Now,
If we pull it outwards, there is a force exerted by the string that is directed towards the equilibrium position.
If we push the spring inwards, there is a force exerted by the string towards the equilibrium position.
Harmonic Motion
In each case, we can see that the force exerted by the spring is towards the equilibrium position. This force is called the restoring force. Let the force be F and the displacement of the string from the equilibrium position be x.
Therefore, the restoring force is given by, F= – kx (the negative sign indicates that the force is in opposite direction). Here, k is the constant called the force constant. Its unit is N/m in S.I. system and dynes/cm in C.G.S. system.

Answer:
Explanation:
simple harmonic motion
Simple Harmonic Motion being definition of any object in equilibrium that moves in a sinusodal wave manner across a point of equalibrium (shown by the equation X = Xo+A*Sin(wt). Analogous to male masturbation, because of its repetitive, sinusodal wave manner of movement.
