Question

On what factors does the inertia of a body depend ? which has more inertia , a cricket ball or a
rubber ball of the same size ?

Answer 1

Answer:

Moment of inertia of a body depends on the body's mass distribution and the axis of rotation.  The moment of inertia of a body is directly proportional to its mass and increases as the mass is moved further from the axis of rotation.

Inertia is the ability of a body to oppose a change in its state.

It is measured by the mass of the body.

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

Answer 2

Answer:

Inertia only depends upon mass.

As we know that a cricket ball will have greater mass than a rubber ball therefore cricket ball will have greater inertia.
