... There is an analogy between the kinetic energies associated with linear motion (K = 1/2 mv 2) and the kinetic energy associated with rotational motion (KR= 1/2 I2) Rotational kinetic energy is not a new type of energy, the form is different because it is applied to a rotating object The units of ro ...
