Question

an oscillatory motion is always periodic but a periodic motion is not always oscillatory explain with an example​

Answer 1

Explanation:

an oscillatory motion is always periodic but a periodic motion is not always oscillatory .oscillatory motion is the to and fro motion of the body where has periodic motion is type of motion in which the motion repeats itself after fixed interval of time for example the pendulum of the clock always repeat its motion after every ffixed time intervalthis motion is oscillatory motion and its periodic also as the pependulum again repeats it's motion the revolution of earth around the sun is a periodic motion as the Earth revolves around the sun after every 365 days but its not a oscillatory motion as it motion is not to and fro this shows that an oscillatory motion is always periodic but a periodic motion is not always oscillatory

Answer 2

Answer:

(1) Periodic motion : A motion that repeats itself at

definite intervals of time is said to be a periodic

motion.

Examples: The motion of the hands of a clock, the

motion of the Earth around the Sun.

(2) Oscillatory motion: A periodic motion in which a

body moves back and forth over the same path,

straight or curved, between alternate extremes is

said to be an oscillatory motion.

Examples: The motion of a taut string when

plucked, the vibrations of the atoms in a molecule,

the oscillations of a simple pendulum.

[Note: The oscillatory motion of a particle is also

called a harmonic motion when its position, velocity and

acceleration can be expressed in terms of a periodic,

sinusoidal functions-sine or cosine, of time.]
