Mr. Andersen describes visible light while discussing the electromagnetic spectrum. A simple description of the eye, optical illusions and lights are also included.Read More
Mr. Andersen explains the simple principles behind simple machines. He shows how the mechanical advantage of a simple machine can increase the input force. A brief discussion of work is also included.
Mr. Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems.Read More
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.Read More
Mr. Andersen shows you how to read a position vs. time graph to determine the velocity of an object. Objects that are accelerating are covered in this podcast. He also introduces the tangent line (or the magic pen).Read More
Mr. Andersen shows you how to interpret a position vs. time graph for an object with constant velocity. The slope of the line is used to find the velocity. A phet simulation is also included.Read More
