If an object moves such that it repeats its path regularly after equal intervals of time, it's motion is said to be periodic. Periodic Motion. The bob of a pendulum repeats its motion regularly after fixed intervals of time. It is due to the reason that the oscillatory motion is called harmonic motion. If the wave is propagated with a velocity v and has a wavelength λ, then the period T is equal to wavelength divided by velocity, or T= λ/v. This motion is called periodic motion. The frequency f is the reciprocal of the period; thus, f = 1/T = v/λ. Thus, the earth has three types of motion at the same time i.e. • The period T is the minimum time interval in which periodic motion repeats, and the amplitude A of the motion is the magnitude of the maximum displacement of the moving object from its equilibrium position.
