Momentum

Hi. It’s Mr. Andersen and this AP Physics essentials video 49. It is on momentum which is just the product of the mass of an object times its velocity. In 1895 a train was headed towards Paris. They were a little bit behind schedule, did not apply the brakes in time and it came shooting […]

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. […]
