Answer: Displacement.
- A Speed
- B Distance
- C Mass
- D Displacement
Correct answer: D. Displacement
Explanation: Displacement has both magnitude and direction, making it a vector. Speed, distance, and mass are scalars.
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.
