An introduction to the quantum behavior of light, specifically the polarization of light. The emphasis is on how many ideas that seem "quantumly weird" are actually just wave mechanics, applicable in a lot of classical physics.

How do you write the linear combination of unit vectors? How do you write the unit vector in the same direction as a given vector? What are the standard unit vectors? This video answers all of these questions and tells you all the basics...

How do you write complex numbers in polar form? If they are in polar form, how do you rewrite them in argand or rectangular form? This video includes step by step instructions for converting complex values back and forth between these...

How do you add vectors, subtract vectors, and use a scalar on vectors? This video shows how to do all of these vector operations both algebraically and graphically. This video is for a precalculus class

How do you find magnitude and direction of a vector? How do you write a vector in component form? This video will discuss how to find all of the above. We define vector, component form, magnitude, direction, standard position, and...

What is the polar coordinate plane and how do we convert points between rectangular and polar form? We start this video by graphing polar points, then we learn how to convert between polar and rectangular/Euclidean form.

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

This video covers: - What a resultant force is - What free body diagrams are - How to calculate the resultant force from a free body diagram - The idea of splitting up the forces into horizontal and vertical components General info: -...

Electric Field Due to a Ring of Charge

This video shows how to find the magnitudes of reaction forces of pins. A general approach to this question is to 1) draw a FBD 2) use Mtotal = 0 and Ftotal =0 3) solve the algebra. A few things to note are: Pin supports apply external...

Here I prove the result that the sum of moments about the center of mass = I_G alpha and the sum of moments about a fixed point = I_o alpha.

Solve a word problem using vectors, airplane and wind

Forces are vectors and can be summed together by adding their x, y and z components together. This can be done graphically or analytically. This problems solves this analytically.

Part two of the series on Raphael's The School of Athens, located inside the Vatican Museum in Vatican City. We examine the forces required to hold the arches in place, and look at how this enhances the composition.
