Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 2 - No. 11)
If the gradient of a speed-time graph is zero, what can be concluded about the object's motion?
The object is at rest.
The object is accelerating.
The object is moving at a constant speed.
The object is decelerating.
Selitys
A gradient of zero indicates no change in speed over time, therefore, constant speed.
