Work Energy Power

Notes:
WORK ENERGY POWER TEST
Work Defined
Energy Video

Objectives

After studying the material of this chapter, you should be able to:
1. Distinguish between work in the scientific sense as compared to the colloquial sense.
2. Write the definition of work in terms of force and displacement and calculate the work done by a constant force when the force and displacement vectors are at an angle.
3. Use graphical analysis to calculate the work done by a force that varies in magnitude.
4. Define each type of mechanical energy and give examples of types of energy that are not mechanical.
5. State the work energy theorem and apply the theorem to solve problems.
6. Distinguish between a conservative and a nonconservative force and give examples of each type of force.
7. State the law of conservation of energy and apply the law to problems involving mechanical energy.
8. Define power in the scientific sense and solve problems involving work and power.

    5. It most likely varies from mod to mod and it appears that mod 7 has to have the test done by class on tuesday (monday night)

  5. In our notebooks, does the table of contents have to include page numbers or can it simply be a list of the day titles in order?

  6. just to let everyone know, if you ever need to know a due date for a test, scroll to the bottom or the blog and look at the calendar. he almost always puts the due dates on it

  7. Sire Crane, today in class you said a gasoline burning car is only about 18% efficient. On the contrary that is not an answer choice... WHAT TO DO?

  8. Also for #42, the correct answer is not there assuming KE = 1/2mvsquared

  9. Mr. Crane! I took the test and was not happy with my grade so i submitted it again and got a lower score! Will the higher one be the one that goes into the gradebook or should i take it again to try to bring it back up??

  10. Mr. Crane can we go over the work energy power test in class? I was wondering on how some where wrong?
