How can we define Inertial mass, Gravitational mass and Rest mass?
Asked by Sonali Ratha | 8th Nov, 2013, 09:26: PM
Inertial mass: It is the property of matter by which it resists the change in motion. It is defined from Newton's second law of motion.
Gravitational mass: It is the property that reacts to gravitational forces around. It is defined from Newton's law of gravitation.
Rest mass: The mass of a body when it is at rest.
According to relativity, mass of a body changes as the speed of the body approaches the speed of light. Hence, the mass when it is at rest is its mass which is the amount of matter contained in it.
There is no difference between the inertial mass and gravitational mass.
