Question

Classify the following as linear , circular, vibratory or oscillatory motion.
i) The motion of a swing.
ii) The motion of earth around the sun.
iii) The motion of a cyclist on a plain road.
iv) The motion of a falling stone
v) The motion of a plucked string of a sitar.

Answer 1

Oscillatory motion is the repetitive motion of the system around its fixed point. It is to and fro motion of an object from its mean position. Examples: movement of a spring, alternating current or oscillation of simple pendulum.

i) motion of a swing-oscillatory motion.

ii) motion of earth around the sun--circular motion

iii) motion of cyclist on a plain road-linear motion

iv)motion of a falling stone-vibratory motion.

v) The motion of plucked string of a sitar-vibratory motion.
