If friction is present, mechanical energy will not be
conserved. Part of the mechanical energy will appear as
internal energy, usually in the form of heat. However, the
total energy is conserved if one takes into account the
different forms of energy.
For an object sliding down an incline, the mechanical
energy at the top is equal to the sum of the mechanical energy
at the bottom and the amount of heat generated.
Conservation of Energy, Part 2
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
The book offers a complete review of your AP course, strategies to give you the edge on test day, and plenty of practice with AP-style test questions. It includes full length practice exams modeled on the real test and all the terms and concepts you need to know.
This book includes a review of all the topics tested including vectors, kinematics, fluid mechanics, optics and nuclear physics. Additionally, the book includes two full length tests made complete with descriptive solutions, and quick study tables for Physics B formulas and equations.
