Question

Which has more inertia, a rubber ball or metal ball of same size?

Answer 1

1.Inertia is the tendency of an object to continue in the state of rest or of uniform motion. The object resists any change in its state of motion or rest. When a sudden brake is applied we move forward because of inertia. You feel the backward push when the bus starts from rest. This is because of inertia.

2.Inertia is the property by which an object resists change in its state of rest or motion. Inertia is dependent upon mass of the body. More the mass of the body, more is the inertia.

3. Final Answer

Among metal ball and rubber ball, metal ball has more mass than rubber ball. Hence metal ball has more inertia than rubber ball
