The angular velocity and amplitude of simple pendulum are ω and r respectively. At a displacement x from the mean position, if its kinetic energy is T and potential energy is U, find the ration of T to U.

The average total energy in one time period of a particle of mass m executing SHM of amplitude a and angular velocity ω is

A simple pendulum of length 'l' has maximum angular displacement 'θ'. The maximum kinetic energy of the bob of mass 'm' is : (g = acceleration due to gravity)

A simple pendulum with a bob of mass m swings with an angular amplitude of 40 degree. When its angular displacement is 20 degree, the tension in the string is greater than mg cos 20
