Angular Momentum of a System
In this video Paul Andersen explains how the angular momentum of a system can be calculated by determining the angular momentum of all individual objects within the system. An inquiry activity using a gyroscope is also included.

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.

Gravitational Forces
In this video Paul Andersen explains how gravitational forces differ from the other three fundamental forces; electromagnetic, strong, and weak. Gravitational forces are always attractive and operate at all scales. Even though...

Coulomb's Law
In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because of...

How Do You Measure the Size of the Universe?
The universe is HUGE. But, there is only so much of the universe we can ACTUALLY see, and if we wanted to measure that FINITE space, how would we do it? A gigantic ruler? One really long car ride? Or maybe it's something even more...

Magnetic Field of a Wire
In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude...

Gravitational Field Strength
In this video Paul Andersen explains how the gravitational field strength is directly related to the mass of the object and indirectly related to the square of the distance from the center of mass. The equation for gravitational field...
