Question

_____ is known as the motion that would take place under the applied force if friction were absent.

(a) Impending motion

(b) Constrained motion

(c) Unconstrained motion

(d) Linear motion

This question was addressed to me by my college professor while I was bunking the class.

Question is from Friction topic in section Work, Energy and Power of Physics – Class 11

Answer 1

Right option is (a) Impending motion

The best explanation: Impending motion is known as the motion that would take place under the applied force if friction were absent. The motion which can’t proceed arbitrarily in any manner is called constrained motion. Motion without any restriction is known as an unconstrained motion. One dimensional motion along a straight line is known as linear motion.
