Rotational Kinetic Energy Formula: Concepts & Solved Examples
WebThe angular moment, L, of a particle with momentum, p, displaced by r from the axis of rotation is L = r X p. Let's take the time derivative. d L /dt = d/dt ( r X p ) = d r /dt X p + r X d p /dt. If the axis of rotation is fixed, then d r /dt is v, which is parallel to p, so the first term on the right is zero. WebThe kinetic energy of a rotating body can be compared to the linear kinetic energy and described in terms of the angular velocity. The extended object’s complete kinetic energy is described as the sum of the translational … timmy needs to eat healthy
