Question

The position verses time graph below represents the motion of an object.

Which one of the four graphs below best represents the velocity verses time graph for this object?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

The slope of $x-t$ graph is velocity.

First, 1. Slope $=0$ (at rest), so $v=0.$
Then, 2. Slope is $-ve$ (moving in $-x$ direction) so, $v$ is $-ve.$
Then, 3. Slope $=0$ (again at rest).
Finally, 4. Slope is $+ve$ (moving in +ve direction) so, $v$ is $+ve.$
