* Newton's Second Law of Motion: This fundamental law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In simpler terms:

* More force = More acceleration

* More mass = Less acceleration

* The Equation: This relationship is expressed mathematically as:

* F = ma

* F represents the net force

* m represents the mass

* a represents the acceleration

In essence, a force causes an object with mass to change its velocity (either speed or direction).
