A scale reads the value of the normal force it exerts.
If you stand on a scale in an accelerating elevator, the
scale will show a weight different than your actual weight:
Apparent weight = m(g + a).
In an accelerating train, a pendulum will not hang
vertically, but rather at an angle with the vertical:
tan(theta) = a/g.
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.
