Calisthenics

• Write a scenario where you are the frame of
  reference and you observe the same jet ski riding
  by at 25 mph and at 0 mph. Hint The jet ski
  never changes speed.

Calisthenics

• If you were the zebra, plot your motion from the
  top picture to the bottom on a distance vs time
  graph. The frame of reference is 10 m from the
  first picture.

  600 meters in 60 seconds, or a tiny warbler that
  travels 60 meters in 5 seconds?

• Cottone is a slow reader. He reads 48 words in 3
  minutes. How fast does he read? Is this a speed?

Calisthenics

• A potato is hurled at a chalkboard. The board is
  10 m away and it takes 1.2 s for impact. What
  was the velocity?

Frame of Reference

• The observer of the motion (does not have to be
  alive- i.e. a tree)
• Book is wrong (can be moving)

Interpreting Distance vs Time Graphs
In all graphs below, Distance is the dependent
variable and Time is the independent variable.

• Which variable is plotted on the x axis?
• Which Variable is plotted on the y axis?
• What type of motion do the above graphs represent?

34
Rules for Interpreting Distance vs Time Graphs
Distance is the dependent variable Time is the
independent variable.

• Rules
• Straight lines mean constant speed.
• - Steeper lines mean faster constant speed.
  Less steep?
• Smooth curves mean acceleration.
• Horizontal line means?

37
Acceleration (Notes)

• Change in speed over time
• Acceleration v t
• Has direction!
• Curve on a distance vs. time graph
• Units- m/s2

38

• Horizontal line means?
• Diagonal line means?
• Curved line means?
