What 2 things does the size of the force depend on?

The size of a force depends on two main factors: Mass and Acceleration

This relationship can be summarized by the equation:

<code> <strong>F = ma</strong>
(_where 'F' = Force; 'm' = mass; and 'a' = acceleration)_
</code>

*Mass = The amount of matter in an object. **Acceleration = The rate at which an object's velocity changes.
