Overview
Inertia is a fundamental concept in physics that describes the resistance of an object to changes in its motion. It is closely related to mass; the more mass an object has, the more inertia it possesses. This means that heavier objects require more force to change their state of motion compared to l...

Example: A stationary ball will not move unless kicked.
Example: A heavier object has more mass and thus more inertia.
Example: Pushing a box to move it.
