Here's a breakdown:
* Inertia is the tendency of an object to resist changes in its motion. This means an object at rest wants to stay at rest, and an object in motion wants to stay in motion at a constant velocity.
* Force is a push or pull that can change the motion of an object.
* To overcome inertia and change an object's motion, you need to apply a force.
Examples:
* A book on a table will stay there unless a force (like a push or a pull) acts on it.
* A car moving at a constant speed will continue moving at that speed unless a force (like braking or friction) acts on it.
