Question
Differentiate between gravitational mass and inertial mass.
Advertisements
Solution
Inertial mass is a measure of inertia of the object. According to the second law of motion F = m X a
m= F/a and this mass is called inertial mass.
Newton law of gravitation gives another definition of mass.
F = (G m1m2)/R2
Thus m2 is the mass of the body by which another body of mass m1 attracts it towards it by the law of gravitation. This mass is called gravitational mass.
