Question

Number of primary equations of motion is ___

(a) 1

(b) 2

(c) 3

(d) 4

This question was posed to me in an international level competition.

This interesting question is from Kinematic Equations for Uniformly Accelerated Motion topic in division Motion in a Straight Line of Physics – Class 11

Answer 1

The correct option is (a) 1

To explain I would say: There are primarily 3 equations of motion. These are v = u + at, s = ut + (1/2)at^2 and v^2 = u^2 + 2as.
