Question
The positions of a ball rolling down an inclined plane at the end of each second are given in the following table:
Plot a displacement-time graph for the motion of the ball. Indicate whether the motion is uniform or non-uniform.
Solution
The displacement-time graph for the motion of the ball is as shown in Fig. below.
Fig. 8.25. Displacement-time graph for non-uniform motion.
The displacement-time graph is a curve, so motion of the ball is non-uniform.
