AThe acceleration of the object
BThe distance travelled so far
CThe velocity of the object
DThe elapsed time of the motion
Answer & Solution
Correct answer: C. The velocity of the object
1. Slope is the rise divided by the run of a straight line.
2. On a position against time graph the rise is a change in position and the run is a change in time.
3. A change in position divided by a change in time is velocity.
4. Acceleration comes from the slope of a velocity against time graph instead.
