1. Graphing Motion

2. How can you find the speed from a distance-time graph?
Slope = rise ÷ run
Speed = distance ÷ time
Therefore:
Distance = rise
Time = run
The slope of a distance-time graph is speed
Y2 – Y1
X2 – X1

3. Speedy Gonzales! Slope = Rise / Run = ? Distance (m) rise run

rise
Distance (m)

4. Bugs Bunny Slope = ? Distance (m) rise run Time (sec) 80 70 60 50 4030 20 10 2 4 6 8 12 14 16
Slope = ?
What’s Bug’s Doing here?
So what’s the speed?
rise
Distance (m)
run
Time (sec)

5. Daffy Duck! Distance (miles) A C B Time (min)
During what time did Daffy rest?
During what time did Daffy walk toward the detector? 40 35 30 25 20 15 10 5 1 2 3 4 6 7 8
When did Daffy walk faster, when moving away or moving toward the detector?
During what time did Daffy walk away from the detector? A
Distance (miles) C B
Time (min)

6. Graphing Motion
A steeper slope on a distance-time graph indicates a higher speed.
