What is a flywheel ?

What is the advantage of a flywheel ?

A flywheel rotating at 420 rpm slows sown at a constant rate 2 rad s^(-2) . What time is required to stop the flywheel ?

Calculate the percentage increase in the moment of inertia about the axis of symmetry of a flywheel when the diameter of the flywheel is increased by 2%.

The mass of a flywheel is concentrated at its rim

The mass of a flywheel is concentrated,at its rim

"The mass of a flywheel is concentrated on the rim ". Why ?

The flywheel of a gasoline engine is required to give up 300 J of kinetic energy while its angular velocity decreases from 600 rev min^(-1) to 540 rev. min^(-1) . What is the moment of inertia of the flywheel ?
