Density is the mass per unit volume: Density =
If a force F acts on a surface of area A, the pressure P on
the surface is P = F/A.
The pressure in a fluid at a depth h is P = P at the
surface + (fluid density)gh.
If an object is placed in a fluid, such as water, the fluid
exerts an upward force on the object; this force is known as
the buoyant force.
Archimedes principle: The buoyant force acting on an object
in a fluid is equal to the weight of fluid displaced by the
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.
