The Mole
In this video Paul Andersen defines and explains the importance of the mole. The mole is simply a number (like a dozen) used to express the massive number of atoms in matter. It serves as a bridge between the mass of a compound and the...

Newton's Three Laws of Motion
Mr. Andersen defines Newton's three laws of motion. He describes how the first law relates to inertia, how the second law relates to mass and acceleration, and how the third law allows a rocket to launch.
