The expression for rigid body’s “rotational kinetic energy” is
SOLUTION:
A body undergoing a rotational dynamics with angular velocity ω will also poses a translational motion. Let the velocity for translation motion be ‘’v’’.
We know for translational motion the energy poses by body is kinetic and given as
Also we know that for a body obeying rotation
v=rω
Substituting in translation
Also there is a relation for moment of inertia i.e
Substituting we get,
