Here's the breakdown:

* Acceleration (a): The rate of change of an object's velocity. It's measured in meters per second squared (m/s²).

* Net Force (F_net): The sum of all forces acting on an object. It's measured in Newtons (N).

* Mass (m): A measure of an object's inertia, or its resistance to changes in motion. It's measured in kilograms (kg).

The Equation:

The relationship between these quantities is expressed as:

a = F_net / m

In simpler words: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means:

* Greater force: A greater force will produce a greater acceleration.

* Greater mass: A larger mass will result in a smaller acceleration for the same force.
