When you multiply an object's mass (m) by its acceleration (a), you get its force (F).

This is described by Newton's Second Law of Motion:

F = m * a

* Force (F) is a push or pull that can cause a change in an object's motion.

* Mass (m) is the amount of matter in an object.

* Acceleration (a) is the rate of change of velocity over time.

So, the greater the mass of an object, or the greater its acceleration, the greater the force acting on it.
