2
Slope

• slope (change in y) / (change in x)
• Slope rise/ run

3
Uniform motion

• Motion with no change in speed or direction
• There are 3 types
• No motion
• Forward (up or to the right)
• Backward (down or to the left)

4
Distance/ Time Graphs

• No motion Distance stays the same while time
  continues on.
• No slope

5

• Forward motion to the right or straight up
• What is the difference between these two graphs?
  Both forward, but one is moving faster (3)
• Positive slope

6

• Backward motion to the left or downwards
• Negative slope

7
What do you think is going on here?
8
The motion formula

• Velocity is defined as the rate of change of
  position.
• V change in position
• time interval
• V df di
• tf - ti
• The slope of a displacement/time graph velocity

Practice

1. At 7am the temp was 6oC, at 3pm it is 12 oC, what
   was its rate of change?
2. A hummingbird can fly at a velocity of 16m/s. If
   it flew for 12s, how far did it travel?
3. A car drove for 20s for 20m. It then traveled
   with a rate of 0.62m/s for 1.5minutes, what was
   the final distance traveled by the car?
