Maxwell's Equations: Crash Course Physics
In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed...

Electric Field of a Sphere
In this video Paul Andersen explains how the electric field strength decreases as the square of the radius as you move away from a point charge, or a uniform distribution of charge on a sphere. This is a direct application of Coulomb's Law.

Forces
Forces are pushes or pulls on an object. Forces can be determined by measuring the motion of an object. If an object accelerates then a force is present.
