प्रश्न
What can you say about the motion of a body if:
its displacement-time graph is a straight line ?

उत्तर
The body has uniform velocity if its displacement –time graph is a straight line. If the straight line is parallel to the time axis then the magnitude of uniform velocity is zero.

Using a speed- time graph
(i) In speed time graph uniform motion is given by a straight line parallel to x axis so figure (a) denotes the uniform motion.
(ii) In speed time graph motion with increasing speed is shown by straight line with positive slope so figure (c) denotes the motion with speed increasing.
(iii) In speed time graph motion with decreasing speed is shown by straight line with negative slope so figure (b) denotes the motion with speed decreasing.
(iv) In speed time graph motion with oscillating speed is shown by zigzag line so figure {d) denotes the motion with speed oscillating.
