Question
The velocity-time graph is a straight line passing through the origin. What is/are the possible state(s) in which a body can appear to exist with this one condition satisfied?
a. Uniformly accelerated motion
b. Stationary
c. Uniform motion
- Only a and b are correct
- Only b and c are correct
- Only a and c are correct
- Nothing is incorrect
Hint:
Option a and b are the correct options for this condition.
The correct answer is: Only a and b are correct
- For velocity-time graph, a straight line passing through origin can represent two possible conditions.
- First condition, if the slope is increasing uniformly with respect to time it can be said that body is in uniformly accelerated motion.
- Second condition, if the slope from origin is parallel to X-axis it can be said that there's no change in velocity with time. Hence, it proves that body is not moving.
