GENERAL PHYSICS at GREAT AMERICA 2010—Application of Physics to Real Life

Goals (Work in groups of 3 or 4 people from your class period only) DUE: TUES. May 11

  • Each group presents to the class (10 min) an analysis attwo of the places below (of the teacher’s choosing) Analyze either a PERSON or the VEHICLE the person is riding in/on.
  • Demonstrate your expertise by responding to teacher questions about your information

Places to Analyze

Each grouppresents an analysis of TWO of the following places: (Teacher’s choice) / Measured Quantities
(or, if necessary, estimated) / Calculated quantities (do all that apply to the places you are analyzing)
You MUST be accelerating at each of these places:
  1. Top of a hill
  2. Bottom of a hill
  3. Around a horizontal Circle
  4. Along any straight horizontal line
  5. Along any straight incline or decline
  6. Swinging on a swing
  7. Any projectile at various locations in its path, including during launch (velocity must have vertical and horizontal components)
/
  • Distances (length, radius)
  • Displacement
  • Mass
  • Time
  • Weight
  • Acceleration (using an accelerometer during horizontal motion only)
  • Angles
  • Other
/
  • Velocity (average; instantaneous, change in velocity)
  • Height (change in vertical position)
  • Energy transfer between two locations (kinetic, gravitational, dissipated, chemical, other)
  • Linear Acceleration
  • Centripetal Acceleration
  • Forces (gravitational, tension, normal, friction, etc.)
  • Net Force
  • Impulse
  • Momentum, change in momentum
  • Power
  • (optional) Relativistic Time Dilation

Procedure

BEFORE YOU COLLECT DATA:

  1. Decide what you need to measure, what you need to estimate, and what you need to calculate at each location.
  2. Decide how you will make your measurements, estimates and calculations.
  3. Decide who will do what. Have a back-up plan.

AFTER YOU RETURN

  1. Prepare a presentation (whiteboard, poster, powerpoint, etc.) of the two places your group analyzed that includes the items below
  2. The name of each place you are analyzing, and where in Madison this occurred. (e.g. Swing at Vilas Park)
  3. A diagram of each place with relevant quantities labeled –you must be accelerating at the places you analyze.
  4. Force diagrams (one for each of the two locations), fully labeled
  5. Energy charts (at least 2 charts for each location), fully labeled, with quantities.
  6. Measured quantities: Show raw data (multiple trials) and describe what instruments you used for each measurement. Include an estimate of uncertainty in each measurement.
  7. Provide a detailed description of how each measurement was made. (You may verbally describe #6 instead of writing this on a whiteboard.)
  8. Estimated quantities: include your reasoning in making each estimate.
  9. Calculated quantities: the equation you used, numbers substituted, and the answer with units.

Available Tools (prepared and supplied by you)

  • stop watch
  • protractor with string and hanging weight (height-finder or horizontal accelerometer (flat surfaces only!))
  • Tape measure or 2 - ? m long string to be used to measure distances
  • know your own pace so you can pace out distances
  • calculator, pens, notepad/notecards, pocket protector, fanny pack

The Project will count 5% of your Semester II grade

Scoring Critera
