Answer: displacement.
- A displacement
- B path distance
- C average speed
- D elapsed time
Correct answer: A. displacement
Explanation: Displacement is the straight-line vector from start to finish, unlike the total path distance.
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.
