Best Answer

In absence of any external force, the body would oscillate indefinitely with a constant amplitude a, then it is called free oscillation.

When a body, being acted by an external periodic force ,oscillates with the frequency of the force, then the oscillation of the body is called forced oscillation.

What is the difference between underdamped and overdamped oscillations?

Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.
