Mr. Andersen explains how sound waves are created and perceived. A brief discussion of pitch and loudness are included. A generated sound of varying pitches is also included.
Mr. Andersen introduces the concept of waves. Both transverse and logitudinal waves are described. The relationship between wave speed, wave frequency and wavelength is also included.
Mr. Andersen explains the law of superposition and the principle of original horizontality. He uses an animation to explain how rock layers can accumulate over time.
Mr. Andersen describes how plate tectonics shapes our planet. Continental and oceanic platers are contrasted and major plate boundaries are discussed.
Mr. Andersen contrasts series and parallel electrical circuits. A simulation is used to visualize electron flow through both circuit types.
Mr. Andersen describes the relationship between voltage, current and resistance in an electric circuit. Ohm's Law is introduced through a circuit simulation.
Mr. Andersen introduces the topic of electricity. He differentiates between static electricity and current electricity. An introduction to electric circuits is also included.
Mr. Andersen explains the difference between potential and kinetic gravitational energy. He also uses physics to calculate the energy in various objects.
Mr. Andersen defines the terms energy, work and power. He also uses a simple example to calculate both work and power.
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 explains the concept of momentum. He also shows you how to solve simple momentum problems. He finally shows you how momentum is both conserved and relative.
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.
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.
Mr. Andersen describes the two portions of the AP Biology Test. Tips for answering multiple choice and free response questions are included. Sample questions from old AP tests are also included.
Mr. Andersen explains the importance of physics as a science. History and virtual examples are used to give the discipline context.
Mr. Andersen explains the differences between scalar and vectors quantities. He also uses a demonstration to show the importance of vectors and vector addition.
Mr. Andersen explains the basic quantities of motion. Demonstration videos and practice problems are also included. The difference between scalar and vector quantities is also discussed.
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).
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.
Mr. Andersen explains how carbon-14 dating can be used to date ancient material. The half-life of radioactive carbon into nitrogen is also discusse
