• B. oscillatory motion
• C. cyclic motion
• D. none of these

Answer 1

Answer: (B)

oscillatory motion

Periodic motion is defined as the motion which is repeated identically after a fixed interval of time , to and fro motion is not necessary here .

Oscillatory motion is that motion in which body moves to and fro about a fixed point in a fixed interval of time .

In a cyclic motion , body returns at its initial position after a time .
