Two cars A and B move along straight lines. Their position-time graphs are shown.  Both cars have CONSTANT velocity. The one with HIGHER velocity has:
AThe same slope as the other
BA steeper line (larger slope)
CA flatter line (smaller slope)
DA curved line
Answer & Solution
Correct answer: B. A steeper line (larger slope)
Slope on a position-time graph = velocity. A steeper line means greater velocity (more distance covered per unit time). The image shows two straight lines of different slopes — the steeper one belongs to the faster car. Figure: Wikimedia Commons, CC — public alternative to NCERT diagrams.
