Force equals mass times acceleration.

F = m * a

This means:

* Force (F): The push or pull on an object.

* Mass (m): How much "stuff" is in an object (how heavy it is).

* Acceleration (a): How quickly an object's speed or direction changes.

In simpler terms:

* The more force you apply to an object, the faster it will accelerate.

* The heavier an object is (more mass), the harder it is to accelerate.

Examples:

* Pushing a heavy box requires more force than pushing a light box.

* A car will accelerate faster if you press on the gas pedal harder.

* A bowling ball will roll slower than a tennis ball because it has more mass.
