What is the slope of a straight-line graph of position versus time?
AAcceleration
BDisplacement
CDistance
DVelocity
Answer & Solution
Correct answer: D. Velocity
1. Slope is rise over run, and on this graph that is change in position over change in time.
2. Change in position over change in time is exactly the definition of average velocity.
3. So the slope of a straight-line position vs. time graph is the velocity.
