Question

Consider two rocks with masses of 1 and 10 kilograms. What is the relation between their inertias? Between their masses? Between their weights on Earth?

Answer 1

The greater mass the object has the greater its inertia would be. As inertia becomes greater, the same happens with the force which is needed stop motion. Linear motion and rotational motion are quite different, because the first one depends only on mass while the second embraces mass, size and shape of an object. According to the information I shared, one will not be able to stop 10 kg mass due to far greater inertia than object of 1kg mass.

Hope you will find it helpful.
