How is inertia taking place if a penny is at rest?
Citrus2011 [14]

A penny is at rest is experiencing  inertia because it is not moving.

<h3>What is inertia?</h3>

According to Newton's first law of motion, every object at rest or uniform motion in a straight line will continue in that state unless it is acted upon by an external force. This law is also called law of inertia.

Inertia depends on mass because the more massive an object is, the more reluctant it will be to move.

Thus, a penny is at rest is experiencing  inertia because it is not moving.
