Newton's Second Law of Motion states that the force acting on an object is directly proportional to its mass and acceleration.

Here's a breakdown:

* Force (F): The push or pull that causes a change in motion. Measured in Newtons (N).

* Mass (m): A measure of an object's resistance to changes in motion. Measured in kilograms (kg).

* Acceleration (a): The rate of change of velocity. Measured in meters per second squared (m/s²).

The equation for Newton's Second Law is:

F = m * a
