# SAQ : State Newton’s second law of motion and use it to define the unit of force in the CGS system

Question

State Newton’s second law of motion and use it to define the unit of force in the CGS system.

Newton’s second law of motion states that the acceleration of a body is directly proportional to the force acting on it and inversely proportional to its mass.

Mathematically, F = ma, where F is force, m is mass, and a is acceleration.

In the CGS system, the unit of force is defined as the dyne, which is the force required to impart an acceleration of 1 cm/s2 to a body of mass 1 gram.
