Physics for IGCSE & O level - Forces And Motion (Section 1 - No. 42)
Which of the following is TRUE about motion graphs?
The slope of a distance-time graph represents speed.
The area under a speed-time graph represents displacement.
A horizontal line in a distance-time graph represents constant speed.
The slope of a velocity-time graph represents acceleration.
Объяснение
Slope distance-time is speed, area speed-time is displacement, and slope of a velocity-time graph is acceleration.
