... There is an analogy between the kinetic energies associated with linear motion (K = ½ mv 2) and the kinetic energy associated with rotational motion (KR= ½ 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 rota ...

... For SHM, the period does not depend on the amplitude. For a pendulum with small , this is true, so a pendulum exhibits SHM for small displacements. For large (greater than 15 degrees or so) the smallangle approximation is not valid and the period does depend on the amplitude (max). Example 11-8 ...
