Question

In uniformly accelerated motion, how many variables are required to fully describe the system?

(a) 1

(b) 3

(c) 4

(d) 2

The question was posed to me in an internship interview.

I need to ask this question from Kinematic Equations for Uniformly Accelerated Motion in portion Motion in a Straight Line of Physics – Class 11

Answer 1

The correct option is (b) 3

To explain: In uniformly accelerated motion, at least three variables are required to completely define the system This can also be found out by using the equations of motion. For finding out the value of any variable, we need at least three known quantities.
