Question
The velocity-time graph of a body is a straight-line coinciding with the x-axis (time-axis). What is the state of the body?
- Uniform motion
- Stationary
- Accelerated motion
- Decelerated motion
Hint:
For velocity-time graph, a straight-line coinciding with X-axis represents no change in velocity. Hence, it clears that body is stationary.
The correct answer is: Stationary
In velocity-time graph, if slope is going down it represents decrease in speed. If slope is going up it represents increase in speed. If it's parallel to time axis it depicts a uniform motion. If it's coinciding to X-axis, it shows that body is in stationary state.
