Mass and Weight

Inetria of mass
The mass of the body defined by Netwon's Seond law of motion is called inertial mass.From
Newton's 2nd law, if a force F applied on the body produces acceleration a on it, then, we have F=ma.

here quantity m is called the inertial mass of the body.Thus, the inertial mass (m)=F

Suppose the same force is applied on two bodies. The body in which the accleration produced is less has more inertial mass than that of teh body in which the accn is produced is more.

Thus, the inertial mass of a body measures of its inertia.It is called as force applied per unit acceleration produced.
