1. Net Force:

* Acceleration is directly proportional to the net force acting on an object. This means:

* More force, more acceleration: A stronger push or pull results in a faster change in velocity.

* No force, no acceleration: If there's no net force acting on an object, it either remains at rest or continues moving at a constant velocity (Newton's first law).

2. Mass:

* Acceleration is inversely proportional to the mass of the object. This means:

* More mass, less acceleration: A heavier object will accelerate less than a lighter object under the same force.

In summary:

* Acceleration = (Net Force) / (Mass)

This is a fundamental relationship in physics known as Newton's Second Law of Motion. It tells us how the forces acting on an object determine its change in motion.
