This is described by Newton's Second Law of Motion:
* F = ma
Where:
* F is the force acting on the object
* m is the mass of the object
* a is the acceleration of the object
This means:
* If you increase the force (F), and keep the mass (m) constant, the acceleration (a) will also increase.
* Conversely, if you decrease the force, the acceleration will decrease.
Example:
Imagine pushing a box across a floor. If you push harder (greater force), the box will accelerate faster. If you push gently (smaller force), the box will accelerate more slowly.
