* Newton's Second Law of Motion: This fundamental law of physics states that the force acting on an object is directly proportional to its mass and acceleration. The equation is:

* Force (F) = Mass (m) * Acceleration (a)

This means:

* Mass: A larger mass requires a greater force to achieve the same acceleration.

* Acceleration: A greater force will produce a greater acceleration for a given mass.

In essence, force is the "push" or "pull" that causes an object to change its velocity (accelerate). The magnitude of the force depends on both the mass of the object and the rate at which its velocity changes.
