If displacement-time graph is a curve, which of the following is correct:
Correct answer: D. gradient of the tangent of graph represents velocity
- A. area under graph represent displacement
- B. gradient of the graph is constant
- C. gradient of the tangent of graph represents acceleration
- D. gradient of the tangent of graph represents velocity
Explanation
If displacement time graph is a curve then the gradient of the tangent of the graph represents velocity because v = x/t

About Displacement and Velocity
Displacement is the directed change in position, while velocity is the rate of change of displacement and includes both magnitude and direction. The topic connects position-time and velocity-time graphs with average and instantaneous values, and distinguishes displacement from distance and velocity from speed.
