If there are no external torques acting on either system, in which case is the final kinetic energy of the system biggest?.

Respuesta :

K.E. of rotation will remain constant if moment of the body is maintained constant.

what is kinetic energy?

A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.

Main body:

This is as per the principle of conservation of angular momentum, i.e.

when T = 0, L= Iω = constant.

K.E. of rotation = 1/2 Iω²

E = I²ω²/2I = L²/2I

where L is constant, therefore, E∝1/I

i.e., K.E. of the system is not constant.

Therefore, moment of inertia of the system increase and K.E. will decrease and vice-versa.

Therefore, K.E. of rotation will remain constant if moment of the body is maintained constant.
