Title: Calisthenics


1
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.

    graph. The frame of reference is 10 m from the
    first picture.

Calisthenics
  • If Eli Manning runs for his life at 10 m/s and
    goes 15 meters, how long was he running?

  • Which has a greater speed, a hawk that travels
    600 meters in 60 seconds, or a tiny warbler that
    travels 60 meters in 5 seconds?

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

10
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?

11
What is the fastest thing on Earth?
  • Other than Cottone

12
First, Lets Talk about Motion
  • Time
  • Distance
  • Frame of Reference
  • Speed
  • Velocity

13
Motion

15
Time
  • Duration
  • Explains how long something lasts

TIME
Its all Relative
18
Speed
  • Distance traveled during a period of time
  • Speed d t

21
Velocity
  • Distance traveled during a period of time
  • Speed d t
  • Has direction!

Velocity vs. Speed
24
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?

  • 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?

36
Graphing
  • P.23 Corrections

37
Acceleration (Notes)
  • Change in speed over time
  • Acceleration v t
  • Has direction!
  • Curve on a distance vs. time graph
  • Units- m/s2

38
Distance vs. Time Graph
  • Horizontal line means?
  • Diagonal line means?
  • Curved line means?
