- Periodic motion Motion which repeats itself after regular intervals of time
- Oscillatory motion A body in oscillatory motion moves to and fro about its mean position in a fixed time interval.
Period (T): It is the interval of time after which a motion is repeated. Its unit is seconds (s).
- Time period Time required for one complete oscillation
- Frequency : Number of oscillations in one second. The unit is Hertz.
An oscillatory motion is said to be simple harmonic, when the displace…
