In this video Paul Andersen explains how free-body diagrams can be used to solve kinematics problems. The only two parts of a free-body diagram are the object and all external forces acting on the object. Numerous situations are...

Today we’re going to talk about the forces that affect a country’s stability. We’ll take a closer look at Costa Rica, Venezuela, Cuba, and Brazil and examine how the cohesiveness of these Latin American countries varies dramatically even...

Why is the electric potential energy of unlike charges negative? Why does it decrease as they get closer? In this Flipping Physics lesson, we graph electric potential energy vs. distance for a two-point charge system and use the shape of...

Derivation for the impulse and momentum formula for a system of particles. Notice that if the sum of external forces = 0 then momentum in the system is conserved!

Conservation of Momentum example 1

This video shows how to calculate the shear force diagrams and bending moment diagrams of a bar under some concentrated loads. I allude to the formulas dM/dx = V at the end, but solve for the values from scratch by drawing and analyzing...

For a system of particles in translational motion, we determine the position, velocity, acceleration, linear momentum, and net force.

This video is a lesson on free body diagrams. It explains what free body diagrams are, the steps involved in making them, and how to use them to analyze both static and dynamic situations. The lesson also covers how to apply Newton's...

Mar.11 -- David Kotok, chairman and chief investment officer at Cumberland Advisors, discusses Federal Reserve and ECB policy, investment strategy, and the outlook for 10-year U.S. Treasury yields. He speaks with Bloomberg's Vonnie Quinn...
