This document provides an agenda and examples for teaching students about motion graphs and distance-time graphs. It includes bellwork examples calculating speed, definitions of speed, distance, and time. It then discusses what distance-time graphs look like for different types of motion including no movement, increasing speed, and returning to the starting point. Examples of distance-time graphs are provided and questions asked about the motion and speeds shown in the graphs.

1. Agenda: Motion Graphs Cornell Notes
Bellwork: James ran 400 kilometers in
24 hours. Calculate his speed.
Kelly skipped 30 meters in 3.5
minutes. Calculate her speed.

2. What are the differences
between Speed and Velocity?

3. How do we calculate Speed,
Distance and Time?
Speed =
Distance
Time
Distance = Speed ´ time
Time =
Distance
Speed

4. What are DISTANCE-TIME GRAPHS?
 Distance-time graphs can be
used to describe journeys.
distance on the vertical (y) axis
time on the horizontal (x) axis.

6. What does a d-t graph look like
with no movement?
Flat

7. How can you tell an object is
moving fast?
Line slopes
up at a steep
angle

8. When the object goes back to the starting
point, what does the graph look like?
Slopes down

9. What does a d-t graph look like for
acceleration (speeding up)?
curved
