Bellwork: James ran 400 kilometers in 24 hours. Calculate
his speed.
Kelly skipped 30 meters in 3.5 minutes. Calculate her speed.
What are the differences between Speed and
Velocity?
How do we calculate Speed, Distance and Time?
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.
What does a d-t graph look like with no movement?
Flat
How can you tell an object is moving fast?
Line slopes up at a steep angle
When the object goes back to the starting point, what does the graph
look like? Slopes down
What does a d-t graph look like for acceleration (speeding
up)? curved
