1. Graphing Motion

2. 2 Variables must be recorded to graph motion:
-position
-time
This allows you to plot a Position-Time Graph.

3. Slope = Rise
Run
= ∆y ∆x
= ∆d ∆t
= Velocity d t

4. The slope of a position-time graph is the velocity of an object
UNIFORM VELOCITY (constant velocity)
Line is straight and slope (anywhere) on the line is velocity

5. Constant Velocity Graph Shapes
Horizontal Line:
- Slope is zero
- velocity is zero
- Object is at rest
Steeper slope:
- Greater Velocity
Negative Slope:
velocity is negative
Negative indicates object is moving
in opposite direction.

6. Example: Position-Time Graph
In which section are you likely traveling the fastest?
Calculate: vAB, vBC, vCD, vDE

7. If the motion is “NON-UNIFORM”, you can find the average velocity by joining 2 points on a graph and finding the slope of the line (a tangent)
