Question

explain significance of moment of inertia in rotatory motion?

Answer 1

moment of inertia. means that the state in which object is going on for example if a body is moving then if We apply an external force then it stop

The motion in which a object rotates in an orbit

for example earth revolves around sun in a perfect orbit

Answer 2

Answer:

Mass increases

Explanation:

As the mass increases inertia become larger. The force required for producing the linear acceleration will also increase. In rotational motion greater the moment of inertia, requires angular acceleration will more torque
