Question

Establish the relation between angular momentum and rotational kinetic energy

Answer 1

How about we bear on frantically working out conditions applying to rotational motion by substituting the fitting rotational factors into the straight-line motion conditions. Work is force times relocation, so for revolution work must be torque times angular d. displacement:

kinetic energy: KE = 1/2 mv2 (transitional) KE= 1/2 Iw2 (rotational)

Angular momentum is corresponding to the snapshot of inertia, which relies upon the mass of a turning object, as well as on how that mass is disseminated with respect to the hub of the rotation. This prompts some fascinating impacts, as far as the preservation of angular momentum.

Angular Momentum L = Iw
