Kinetic energy of rolling body class 12 NEB

Kinetic Energy of a Rolling Body

If an object is rolling without slipping, then its kinetic energy can be expressed as the sum of the translational kinetic energy of its centre of mass and the rotational kinetic energy about the centre of mass.

The translational kinetic energy of a rolling body is:

(K.E)T = ½ mv²

The rotational kinetic energy of a rolling body is:

(K.E)R = ½ I₀ω²
