Problem
A student is asked to study the motion of a toy car moving at uniform speed along a straight track. a. (i) Define uniform speed. b. (ii) Describe and sketch the general shape of the distance–time graph for this motion, clearly labelling both axes. c. (iii) Explain how the speed of the car can be obtained from the distance–time graph.Intuitive explanation
The key here is understanding uniform motion — when an object travels at constant velocity, its position changes by equal amounts in equal time intervals. Rather than thinking about forces or acceleration, focus on the simple relationship between distance, speed, and time: . This linear relationship is your tool for predicting where the car will be at any moment or how long a journey takes.
