Introductory Kinetic Friction on an Incline Problem

– Good morning. We are going to determine the coefficient of kinetic friction between the book and the incline, given the following information. ♫ Flipping Physics ♫ – [mr.p] Bo, please tell me what we know. – Well, it looks like the angle of the incline theta is 14 degrees, the change in time is […]

Potential Energy

Hi. It’s Mr. Andersen and this AP Physics essentials video 81. It is on potential energy. Let’s say I take this crate right here and I add a cable to it and I raise it up. Does that crate now have potential energy? It does assuming it is sitting on the earth because if I […]

Review of Momentum, Impact Force, and Impulse

– Good morning. We need to review conservation of momentum, impulse, impact force, and when to use all of these equations. ♫ Flipping Physics ♫ – But first, nice dance costumes everybody. (party horn and applause) – [Group] Dance costume day. – Bobby, what is the equation for conservation of momentum? – The sum of […]

Deriving the Work-Energy Theorem using Calculus

– Good morning. Today we are going to use calculus to derive the work-energy theorem. And I do understand because this is an algebra-based class that many of you have not taken calculus yet. However, I consider it important to sometimes see math which is a little bit more advanced than what you currently understand. […]

Introduction to Mechanical Energy with Friction

– Good morning. We have already learned about conservation of mechanical energy. ♫ Flipping Physics ♫ Remind me, Billy, when can we use the conservation of mechanical energy equation? – I actually don’t remember. – Mechanical energy is conserved when there’s no work done by friction and– – There is no work done by the […]

Kirchoff’s Loop Rule

Hi. It’s Mr. Andersen and this AP Physics essentials video 87. It is on Kirchhoff’s Loop Rule which is a powerful tool to look at circuits. And when combined with Kirchhoff’s Junction Rule, which we will get to in a few videos, it really makes analysis of complex circuits possible. And so the way it […]
