Question 6 — The position-time graph for - Questions at the end of the chapter - Chapter 6 - How Forces Affect Motion (Exploration)

Last updated at June 28, 2026 by

The position-time graphs of four objects A, B, C and D moving along a straight line are given (Fig. 6.37). On which object does a net force act? (i) A (ii) B (iii) C (iv) D
View Answer Hide Answer

The correct option is (iii) Object C.

A (straight sloping line) and D (straight line) show constant velocity, and B (flat line) is at rest — all have zero net force. Only C has a curved position-time graph, meaning its velocity is changing, so a net force acts on it.
