10/1 Warm Up

Time is always plotted on the X-axis (bottom of the graph). The further to the right on the axis, the longer the time from the start.

Distance is plotted on the Y-axis (side of the graph). The higher up the graph, the further from the start.

Time is increasing to the right, but its distance does not change. It is not moving. We say it is At Rest.

Speed-Time graphs look much like DistanceTime graphs. Be sure to read the labels!! Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis.

A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. 

A straight line does not mean that the object is not moving!

1. Below is a distance time graph that shows the motion of a student on a walk. Which statement best describes the students' motion?

• A. The student walks slowly at first, then increases their speed, stops, and very quickly returns to the starting point.

• B. The student walks up a hill at the beginning, and then has a flat surface, and then walks down a hill at the end.

• C. The student is going faster and faster in the last two minutes.

• D. The student starts out moving very fast, slows down in the middle of the walk, and then speeds up again at the end.
