Answer: Distance or displacement.
- A Velocity in routine practice
- B Acceleration overall
- C Distance or displacement
- D Force in most cases
Correct answer: C. Distance or displacement
Explanation: Area under v-t graph equals displacement. If the graph goes below the axis, that area is negative displacement.
On a velocity-time graph for uniform acceleration, the slope of the line gives the acceleration and the shaded area under the line gives the displacement.
