प्रश्न
Can you suggest the kind of motion of a body from the following distance – time graph?

उत्तर
Distance – time graph in the figure shows that initially, the body is in uniform motion i.e. it covers equal distance in equal intervals of time.
From O to A, the body is in uniform motion, and from A to B, the body is at rest.

How can you find the following?
Velocity from a displacement – time graph.
From the displacement – time graph shown given below calculate:
- Average velocity in the first three seconds.
- Displacement from the initial position at the end of 13 s.
- Time after which the body is at the initial position,
- Average velocity after 8 s.
Show the difference between distance and displacement with the help of a diagram.
