For a body rotating with constant angular velcoity, its kinetic energy is directly proportional to the square of its

Text Solution

Verified by Experts

Angular momentum of a body , `L = Iomega` ( in magnitude)
`therefore` Rotational kinetic energy of a body.
`E = (1)/(2)Iomega= (1)/(2)(Iomega)omega = (1)/(2)Lomega = (1)/(2)L((L)/(1))= (1)/(2)(L^(2))/(I)`
