A torque T acts on a body of moment of inertia l rotating with angular speed `omega`. It will be stopped just after time

The relation between the torque tau and angular momentum L of a body of moment of inertia I rotating with angular velocity omega is

The relation’ between the torque r and angular momentum L of a body of moment of inertia I rotating with angular velocity omega is

A flywheel of moment of inertia I is rotating with uniform angular speed omega . If a torque tau retards the wheel, then the time in which the wheel comes to rest is

An ice skater having moment of inertia l rotating with angular speed omega suddenly opens her arms, which reduces her angular velocity to (omega)/(4) . Calculate the change in moment of inertia of the dancer.

An ice skater having moment of inertia l rotating with angular speed omega suddenly opens her arms, which reduces her angular velocity to (omega)/(4) . Calculate the change in moment of inertia of the dancer.

An ice skater having moment of inertia l rotating with angular speed omega suddenly opens her arms, which reduces her angular velocity to (omega)/(4) . Calculate the change in moment of inertia of the dancer.

Express torque in terms of moment of inertia and angular acceleration.

If no torque acts on a rotating body and if its moment of inertia decreases the angular velocity omega of the body increases such a manner that

A disc of moment of inertia I_(1) is rotating freely with angular speed omega_(1) when another non-rotating disc of moment of inertia I_(2) is dropped on it. The two discs then rotate as one unit. Find the final angular speed.
