Understanding the Concept

The area under a velocity-time graph provides critical information about an object's motion. To decipher the meaning of this area, it's essential to understand the relationship between velocity, time, and displacement.

Explanation of Options

1. Displacement: Displacement is defined as the overall change in position of an object, which can be found by calculating the area under the velocity-time graph.
2. Acceleration: Acceleration is the rate of change of velocity over time, but it is not represented by the area under the graph.
3. Change in Velocity: While the area does relate to the motion, it does not directly express the change in velocity but rather reflects the total movement over time.
4. Change in Acceleration: This concept is related to how the velocity changes over time but does not correspond to the area under the curve.
5. Speed: Speed is the magnitude of velocity and does not represent the area under the graph.

Conclusion

Based on the explanation, the area under a velocity-time graph clearly represents displacement.

Final Answer

Displacement
