In rotatory motion, moment of inertia

What is moment of inertia ?

The rotational kinetic energies of two flywheels are equal. If the ratio of their moments of inertia is 1:9 then the ratio of their’angular momenta is

In rotatory motion, linear velocities of all the particles of a body

Define moment of inertia.State its unit.State the factors on which moment of inertia depends.

A ring and a disc have same mass and same radius. Then ratio of moment of inertia of ring to the moment of inertia of disc is

What are the factor on which moment of inertia depend ?

If the radius of solid sphere is doubled by keeping its mass constant, compare the moment of inertia about any diameter. (1:4)

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

According to the principle of conservation of angular momentum, if moment of inertia of a rotating body decreases, then its angular velocity

The rotational kinetic energies of two bodies of moments of inertia 9 kg m^2 and 1kg m^2 are same. The ratio of their angular momenta is
