Explanation:

Question 14

• The slope of a position-time graph equals velocity (average for straight segments, tangent slope for instantaneous).
• The area under a velocity-time graph calculates displacement.
• The slope of a velocity-time graph is acceleration.
• The area under an acceleration-time graph gives the change in velocity, not velocity itself (it requires initial velocity to find final velocity).

By definition, the integral of velocity over time (area under a velocity-time graph) corresponds to the displacement of the object.

Answer:

The area under an acceleration-time graph gives velocity.
