Question

Which of the following is/are definitely non-linear motion?

• A. Only 1
• B. 1 and 2
• C. 2 and 3
• D. 1, 2 and 3

Answer 1

The correct option is A

Only 1

Both periodic and oscillatory motion can be linear. E.g. the motion of a mass attached to a vertical spring is periodic, oscillatory as well as linear. However, circular motion is always non-linear as the body moves along a circle.
