Question
Observe the pattern of the following graph carefully. The x-axis denotes the time axis, and the physical quantity along the y-axis can be chosen from displacement and velocity. The graph represents ____ and ____ for the y-axis representing displacement and velocity, respectively.
- Uniform motion, uniformly accelerated motion
- Uniform motion, stationary body
- Stationary body, uniform motion
- Stationary body, uniformly accelerated motion
Hint:
The steepness or slope with time represents the change of body's motion and position. If it's a straight line there's something constant.
The correct answer is: Stationary body, uniform motion
- As for Y-axis representing displacement, with passage of time there's no change in position of body. Hence, it is a stationary body.
- As for Y-axis representing velocity, with passage of time there's no change in velocity of body. So, it can be said that body is in uniform motion.
