Molecules in motion possess energy called kinetic energy.

Mechanical energy and kinetic energy

When a particle oscillates in simple harmonic motion, both in potential energy and kinetic energy vary sinusoidally with time. If v be the frequency of the motion of the particle, the frequency associated with the kinetic energy is :

A solid sphere is in rolling motion. In rolling motion a body prosseses translational kinetic energy (K_(t)) as well as rotational kinetic energy (K_(r)) simutaneously. The ratio K_(t) : (K_(t) + K_(r)) for the sphere is

Two bodies A and B having masses in the ratio of 3 : 1 possess the same kinetic energy. The ratio of their linear momenta is then
