In this lesson our instructor talks about linear momentum. First, he discusses an overview of linear momentum. Then he talks about impulse, relationship between momentum and impulse, and the reason for linear momentum. Four complete example problems round up this lesson.
Linear momentum (→p) is the product of both velocity and mass:
Notice that linear momentum uses velocity, not speed. That means momentum is a vector quantity.
The unit for linear momentum is kg ·[m/s].
Impulse (→J) is a way to talk about changes in linear momentum:
The change in linear momentum is equal to the impulse and vice-versa-→J=∆→p.
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.
This book includes a set of features such as Analyzing-Multiple-Concept Problems, Check Your Understanding, Concepts & Calculations, and Concepts at a Glance. This helps the reader to first identify the physics concepts, then associate the appropriate mathematical equations, and finally to work out an algebraic solution.
