Graphs of Uniform Motion
Graphing MotionGraphical techniques are helpful in understanding the concepts of velocity and acceleration.
A car travelling at a constant speed of 20 m/s, will have a position that increases by ____ every second.
A straight line distance versus time graph indicates ______ motion.
The slope of a distance versus time graph indicates the ________ of the object.
The slope of a displacement versus time (or position versus time) graph indicates the _______ of the object.
What does (0, 0) represent in this situation?
If the slope of a distance-time graph was negative - what would this mean?

Ex3: An aimless chemistry teacher wanders as:
Notice that we must label displacement rather than distance; why?
The above graph shows a motion consisting of a uniform velocity in each section. The slopes for each line segment, yields the velocity for that time interval. Find each.
Describe the motion of the above graph.

Describe the motion in these d-t graphs
Recall: Car drove 1.0 km through the country at 100 km/h and then 1.0 km through town at 50 km/h and the average was 67 km/h (not 75 km/h).
Let's graph this motion:
d (km)
t (h)
Slope = ______
Slope = ______
Slope = ______
The slope of a line connecting two points on a d-t graph (straight or curved) is called a secant line and yields the average speed or velocity.
