The linear momentum of an object is a vector equal to the
product of its mass and velocity.
If a force acts on an object for a certain period of time,
the average value of the force times the time interval is the
impulse provided by the force.
In a collision, total momentum before collision = total
momentum after collision.
In an inelastic collision, mechanical energy is not
conserved; part of the internal energy appears as internal
energy of the colliding objects. If two objects stick together
when they collide, the collision is said to be completely
In a ballistic pendulum a bullet penetrates a vertically
hanging block, which then swings to a certain maximum height
whose value depends on the bullets velocity.

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.
