![]() ![]() Mathematically v=1÷T= 2 T constant is called the angular frequency.Ĭonsider a particle of mass m moving along the X-axis. The reciprocal of period is called the frequency, or one can also say that frequency represents the no. If T is period then the reciprocal of T i.e is 1/T is called frequency of periodic motion. The smallest interval of time after which the motion is repeated is called its period. If displaced little from the point, it will perform oscillations in the bowl.Įvery oscillatory motion is periodic motion, but converse is not true.Įxample:- circular motion is periodic but not oscillatory. ![]() ![]() If the body is given small displacement from the position, a force comes into play which tries to bring the body back to the equilibrium point, giving rise toĮxample:-A ball placed in a bowl will be in equilibrium at the bottom. Simple harmonic motion deals with the repetitive nature of the motion of a particle, i.e.”a motion in which restoring force is directly proportional to displacement of the body by its mean position”.Ī motion that repeats itself at regular intervals of time is called periodic motion.Įxample:- When you play the game of bouncing the ball off the ground, between your palm and ground. We know that rectilinear motion and motion of projectiles are non-repetitive, but planetary motion in the solar system and uniform circular motion are repetitive. ![]()
