|Class 11 Physics Oscillations||Introduction|
In this chapter we will learn about oscillatory motion or oscillations. Any motion which repeats itself at regular intervals of time is known as periodic motion. If a body moves back and forth repeatedly about its mean position then it is said to be in oscillatory motion.
For example: The to and fro movement of pendulum, jumping on a trampoline, a child swinging on a swing.
Oscillations can be defined as Periodic to and fro motion which repeat itself at regular intervals of time.
