1. Graphing Motion
Distance Time graphs
(AKA position time)

2. - y-axis represents distance - x-axis represents time
What are distance-time graphs?
Distance-time graphs show how far something travels in a certain amount of time
- y-axis represents distance
(dependent variable)
- x-axis represents time
(independent variable)

3. Use what you learned from the PhET moving man simulation…….
Describe the type of movement for each line segment listed below. 1. 2. 3. 2
positive motion
(up or to the right) 3 1
at rest – standing still
(flat line with no slope)
negative motion
(down or to the left)

4. Straight lines 
constant motion or constant
speed
Curved lines  motion that
is not constant or speed
that is not constant

5. The angle of the line in a graph is the slope
The angle of the line in a graph is the slope. Rank the lines in the graph from highest slope (steep line) to the lowest slope.
_____, _____, _____
A B C

6. A distance time graph may be used to determine SPEED

7. What is the speed for each line in the graph?B. C.
4 m / 1 s = 4 m/s
5 m / 3 s = 1.7 m/s
2 m / 3 s = 0.67 m/s

8. Graph 1
a) Two people head out for a walk. Looking at the graph below, which do you think is walking faster?
red
b) Using the graph, calculate the average speed of each person.
Green person's speed:
Red person's speed:
1.4 m / 2 s = 0.7 m/s
2 m / 1 s = 2 m/s

9. Graph 2
a) Two people head out for a bike ride. Looking at the graph below, which do you think is faster?
purple
b) Using the graph, calculate the average speed of each person.
Purple person's speed:
Yellow person's speed:
6 km / 1 hr = 6 km/hr
4.2 km / 3 hr = 1.4 km/hr
