Main goal:

Be able to describe the difference between the physics definitions of work and power. (5.1-5.3)

Class Agenda:

  1. Power Lab (you should be able to describe the difference between power and work after completing this lab). See answer key above if you were absent or need to review.
  2. Power vs. Work practice problems (pg. 3). See answer key above for corrections.

Homework:

  1. Complete page 3 in Energy packet.

Main goal:

Be able to design an experiment that models the relationship between the mass of a meteor and the amount of energy it releases during impact. (5.4)

Class Agenda:

  1. Review the similarities and differences between work and power.
  2. Discuss selected problems from homework (pg. 3). See answer key above.
  3. Clay Lab. By the end of this lab you should be able to describe the relationship between the mass of an object and the amount of energy it releases.

Homework:

  1. Attempt introductory energy problems (pg. 7). We will go over notes as a class next time.

Main goal:

Be able to use the Law of Conservation of Energy to solve energy-based problems. (5.1, 5.4-5.7)

Class Agenda:

  1. Review clay energy lab. We will mainly discuss what this lab was meant to represent in terms of energy transfer.
  2. Discuss the Law of Conservation of Energy. This is a good video that overviews the concepts of work, energy and power if you were absent or need to review (do not worry about the portion where the instructor mentions calculus!).
  3. Discuss mechanical, potential and kinetic energy concepts and formulas.
  4. Practice using the law of conservation of energy and related formulas (pgs. 6-10).

Homework:

  1. Complete any pages from 6-10 that were not finished in class. See answer key above.

Main goal:

Be able to calculate the amount of energy transferred during a meteor's impact with the earth using experimental data and energy formulas. (5.4-5.7)

Class Agenda:

  1. Review practice problems from homework (pages 6 & 7). See the answer key at the top of the page if you were absent or need to review.
  2. Analyze clay lab data to determine the amount of energy transferred during a meteor's impact with the earth.

Homework:

  1. Complete clay lab analysis

Main goal:

Be able to design and build a roller coaster that models the Law of Conservation of Energy and solve for values at various points using ME, PE and KE formulas. (5.4-5.7)

Class Agenda:

  1. Review clay lab analysis and analyze error.
  2. Design and construct roller coasters
  3. Complete "Roller Coaster Lab" assignment

Homework:

  1. Finish "Roller Coaster Lab"
