Physics for IGCSE & O level - Forces And Motion (Section 5 - No. 47)
Which of the following represents constant speed in motion graphs?
A straight line on a distance-time graph
A curved line on a distance-time graph
A horizontal line on a speed-time graph
A straight line on a speed-time graph with a positive slope.
설명
Constant speed is represented by a constant rate of change, so a straight line on a distance-time graph and a horizontal line on a speed-time graph.
