For uniform motion, velocity is represented by the gradient of a:

1. Velocity is the rate of change of displacement with time. 2. A rate of change is read as the gradient of a graph. 3. So velocity is the gradient of a displacement against time graph. 4. For uniform motion that graph is a straight line, and its constant gradient is the constant velocity. 5. The gradient of a velocity-time graph gives acceleration instead, and its area gives displacement. _Source: NECTA CSEE 2022 Physics 031, Question 1: Multiple Choice, item (v)_
