Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 3 - No. 17)
If the speed of an object is increasing uniformly, what will the shape of its speed-time graph be?
A horizontal line.
A straight line with a positive slope.
A straight line with a negative slope.
A curve.
Explication
Uniformly increasing speed means the object's acceleration is constant, and its speed-time graph will be a straight line with a positive slope.
