A body is undergoing simple harmonic motion if it has an acceleration which is:

(a) directed towards a fixed point, and

(b) proportional to the displacement of the body from that point.

The

The equation for s.h.m. is usually written as acceleration (a) = - ω

where ω is a constant (not to be confused with angular velocity). The value of ω depends on the particular system of oscillation. In our example ω = 0.1.

The uinits for displacement, velocity and acceleration have their usually acepted values.
