Slope of velocity time graph is_____________________?
Correct answer: A. acceleration
- A. acceleration
- B. distance
- C. force
- D. momentum
Explanation
The slope of a velocity-time graph is change in velocity divided by change in time, Δv/Δt, which is acceleration measured in m/s^2. Option a is correct; option b confuses the area under a velocity-time graph, which gives displacement in metres, with its slope.

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.
