" Measurement of mass inertia" - Explain ?

1 Answer

Answer :

If you want to move two objects from a stationary state with two objects of two different masses, more effort will be required in case of heavy objects. Similarly, if two objects are moving, more effort will be required to stop them in the case of heavy objects. This is why it is said that mass is a measure of inertia.
