WebJan 15, 2024 · The movement of an object through space is called translation. To contrast it with rotational kinetic energy, the ordinary kinetic energy K = 1 2 m V 2 is referred to as translational kinetic energy. So, the total kinetic energy of an object that is rolling can be expressed as. (3A.3) K R o l l i n g = K t r a n s l a t i o n + K r o t a t i o n. WebAug 2, 2024 · The rotational kinetic energy of a rolling body is: (K.E) R = ½ I₀ω². Since we know that I₀ = mk² and for rolling ω = v/ r. ( K. E) R = 1 2 m k 2 ( v 2 r 2) = 1 2 k 2 r 2 m v 2. …
WebThus, we can say that the total kinetic energy of a rolling object is the sum of the rotational kinetic energy about the center of mass and the translational kinetic energy of the center …
