Force (F) = Mass (m) x Acceleration (a)
This means:
* A larger mass requires a greater force to achieve the same acceleration. Think about pushing a small car versus a large truck. The truck requires more force to get it moving at the same speed.
* A greater acceleration requires a greater force, even for the same mass. If you want to quickly accelerate a car, you need to apply more force than if you want to slowly accelerate it.
Therefore, force is directly proportional to both mass and acceleration.
