Question

What is preodic motion and oscillatory

Answer 1

period motion   is known as repeating motion  and osciilatory motion is fro and back motion

Answer 2

$\Large{\underline{\underline{\bf{Solution :}}}}$

★ Preodic Motion :

(i) When a body repeats its motion continuously on a definite path in a definite interval of time then its motion is called periodic motion.

(ii) The constant interval of time after which the motion is repeated is called the 'Time period of motion.' (T)

Example : Time period of hour hand is 12 hours.

★ Oscillatory Motion :

(i) If a body in periodic motion moves along the same path to and fro about a definite point (equilibrium position), then the motion of the body is a vibratory motion or oscillatory motion

Note: Resultant force acting on the particle is zero in equilibrium condition.

It is to be noted here that every oscillatory motion is periodic but every periodic motion is not o
