- Velocity depends on both distance and time.
- Constant velocity plots as a straight line on a distance vs. time graph.
- The steepness or slope of the line on the distance vs. time graph is a measure of velocity.
- Acceleration is the addition of velocity with elapsed time.
- Uniform acceleration means that the velocity increases by the same amount in each time interval.
- Accelerated motion plots as a curved line on a distance vs. time graph, but is a straight line on a graph of distance vs. the square of time.
- Increasingly greater distances are traveled in equal time intervals in accelerated motion.
- Uniformly accelerated motion plots as a straight line on a velocity
vs. time graph.

The slope of a graph of velocity vs. time represents acceleration while the area of the graph represents the distance traveled.
