The slope of the curve in the given velocity-time graph represents
Correct answer: D. Instantaneous velocity.
- A. Uniform velocity.
- B. Positive acceleration.
- C. Negative acceleration.
- D. Instantaneous velocity.
Explanation
The slope of a velocity-time graph represents acceleration. If the slope is positive, it indicates positive acceleration, and if it is negative, it indicates negative acceleration. Uniform velocity would be shown by a horizontal line (zero slope), indicating no change in velocity over time. Instantaneous velocity, on the other hand, is the velocity at a specific point in time, not represented by the slope of the graph. Therefore, the correct answer is that the slope of the curve represents acceleration, not instantaneous velocity.

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.
