Editing Simple harmonic motion (section)

=== Oscillatory motion ===
The motion of a body in which it moves to and from a definite point is also called [[oscillatory motion]] or vibratory motion. The time period is able to be calculated by
<math display="block"> T= 2 \pi\sqrt\frac{l}{g}</math>
where l is the distance from rotation to the object's center of mass undergoing SHM and g is gravitational acceleration. This is analogous to the mass-spring system.
