F = m * a

Where:

* F is the net force acting on an object (measured in Newtons, N)

* m is the mass of the object (measured in kilograms, kg)

* a is the acceleration of the object (measured in meters per second squared, m/s²)

Explanation:

This equation states that the net force acting on an object is directly proportional to its mass and acceleration. This means:

* More force: The more force applied to an object, the greater its acceleration will be.

* More mass: The more massive an object is, the less it will accelerate for a given force.

Key points:

* This equation describes the relationship between force and motion in a *linear* system. It doesn't directly apply to rotational motion.

* This equation is a fundamental principle in classical mechanics and explains a wide range of physical phenomena.
