The slope of velocity-time graph gives_______?
Correct answer: C. Acceleration
- A. Speed
- B. Velocity
- C. Acceleration
- D. All of these
Explanation
The slope of a velocity-time graph is change in velocity divided by time, which is acceleration, measured in m/s². The likely mistake is choosing velocity because velocity is plotted on the vertical axis, but the slope represents its rate of change.

About Acceleration
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
