On a displacement-time graph, what does the slope of the line represent?
AAcceleration
BEnergy
CForce
DVelocity
Answer & Solution
Correct answer: D. Velocity
1. On a displacement-time graph, the y-axis records displacement and the x-axis records time.
2. Slope equals change in displacement divided by change in time.
3. That ratio is the definition of velocity.
4. So the slope of a displacement-time graph gives the velocity.
5. Acceleration would be the slope of a velocity-time graph, not displacement-time.
