Question

An observer is sitting on a car moving with some constant velocity. The observer sees things around him, in the ____

(a) Relative frame of reference

(b) Absolute frame of reference

(c) Valid frame of reference

(d) Ground frame of reference

This question was posed to me in an interview.

My enquiry is from Motion in a Straight Line in section Motion in a Straight Line of Physics – Class 11

Answer 1

Right option is (a) Relative frame of reference

The best explanation: The observer is not stationary with respect to ground. The observer is stationary with respect to the frame of the moving car, i.e., to the relative frame of reference. The observer will see everything around him/her with respect to the relative frame of reference.
