Newtonian mechanics–in 60 seconds

Newtonian mechanics–in 60 seconds

Newtonian mechanics!! I got a request to discuss the Schrödinger equation but FIRST I must start with how we understand particles and their position. And this starts with Newtonian mechanics. Next video will be explaining quantum particles. Then explaining waves. Then wave function aka Strödinger equation! But first got to run to my next casting…

Linear Algebra Example Problems – Finding “A” of a Linear Transformation #2

http://adampanagos.org Course website: https://www.adampanagos.org/ala-applied-linear-algebra A linear transformation can always be represented as a matrix operation on some vector x. In this example we’re told values for T(e1), T(e2), and T(e3) where ei are “coordinate vectors”. These vectors have a zero in every coordinate except a single one in their “ith” coordinate. Using this information we…

Newtonian Mechanics: Equilibrium (EF)

Newtonian Mechanics: Equilibrium (EF)

In this video I show how to determine support reactions applying equilibrium concepts. I will explain how to choose a conventional coordinate system that we will use to apply equations of moments and forces at equilibrium. Newton’s principles of equilibrium are implemented along with free-body diagrams. Beer, Ferdinand Pierre. Vector Mechanics for Engineers: Statics and…

Non-newtonian fluid demonstration – with bicycles

Dr. Miha Kos from the House of Experiments ( http://www.h-e.si ) and Dr. Gorazd Planinšič from the Faculty of Mathematics and Physics at the University of Ljubljana ride through a pool of non-Newtonian fluid. A young girl also performs a cartwheel in the same pool. The video was made at the 2009 Sciencetival in Ljubljana,…
