Warmup:

1
Warm-up

• What would a distance vs. time graph for a
  constant speed look like?
• (Make up some data, then plot the data)

Distance Time
Distance (m)
Time (s)
2
Linear Motion Worksheet

• Any Questions?
• Turn em in

3
Kinematics 1 Lab

• You will each create a Rough Draft of every lab
  we work on in class.
• All Rough Drafts must be hand-written by you.
• You cant have one person in your group type up a
  rough draft and make copies for all the group
  members.

4
Kinematics 1 Lab

• Purpose Question How will changing the incline
  angle of a ramp affect the speed that a ball
  rolls on a flat track at the bottom of the ramp?
• (First things firstwrite a background paragraph
  about the ball and ramp.)

5
Kinematics 1 Lab

• Hypothesis (If/then/because format)
• Procedure and Materials list variables
  materials, create a step-by-step method, and draw
  a picture of your testing apparatus.
• Make sure to tell me how youll control all other
  variables other than the MV and the RV.
• Data Table prepare your data table before you
  begin testing

6
Angle of Ramp __________
Distance (m) .45 .90 1.35 1.80
Time Trial 1 (s) Trial 2 (s) Trial 3 (s)
Avg. Time Speed

• You will need three of these (one for each angle
  you choose)
• Choose 3 low angles that are at least 10 apart
  from one another.

7
Kinematics 1 Lab

• Assign jobs to the people in your group.
• Youll need a timer who knows how to take
  accurate split times on the stopwatch
• Before you begin to collect any data, do a couple
  of practice runs.
• Choose 3 low ramp angles that are at least 10
  apart from each other.
• Begin Data Collection when youre ready
• Note any strange or inconsistent results beside
  the data table and describe what happened

8
Your Homework

• By any method you choose, determine your average
  speeds of walking, skipping, and running. For
  each type of motion, include
• The method you used (brief paragraph)
• The data you collected
• The calculations you performed
