A system is isolated if it does not exchange energy with
The total energy of an isolated system is constant in
Energy may be transformed from one form to another. For
example, potential energy may be transformed to kinetic
When a block is attached to one end of a spring and set
oscillating, then at any one instant in time the system will
have a kinetic energy K given by (1/2)(mass)(velocity squared)
and an elastic potential energy U given by (1/2)(force constant
k)(displacement from equilibrium, squared). But the sum K+U
remains constant; it does not change as time goes by.
Conservation of Energy, Part 1
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.
