Differences between inertial Mass and Gravitational Mass

Inertial mass

  • Inertiam mass is measure of opposition to acceleration.
  • It is measured by Newtion's II law of motion.
  • The inertial mass can be measured only when the body is moving.

Gravitational mass

  • Gravitational mass is measure of force of attraction between the body and the earth.
  • It is measured by Newton's law of gravitation.
  • Gravitational mass can be measured when the body is at rest i.e., by using common balance.
