An oscillatory motion is always periodic,but a periodic motion is not always oscillatory'. Explain the statement with an example
Answers
Explanation:
a periodic motion is a motion in which a particle repeats its motion after a fixed time period . for example circular motion , pendulum motion are periodic motions .
meanwhile , an oscillatory motion is a motion in which particle moves to and fro about a fixed point , for example motion of a pendulum .
thus we can say pendulum's motion is both oscillatory and periodic while circular motion is only periodic motion .
so we can say , an oscillatory motion is always a periodic motion but a periodic motion may or may not be an oscillatory motion .
please rate and heart .
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.]
