Velocity in Physics - Meaning, Measurement, & Calculation

Velocity is the rate of change of position. This sixth RP taproot episode lays the 1-dimensional foundation for the study of velocity, acceleration, and all the laws of kinematics.

Types of Force in Physics: Diversity, Meaning, & Measurement (RP5)

Sep 18, 2012   //   by Tucker   //   Radical Physics, RPn  //  Comments Off

Types of Force in Physics - Diversity, Meaning, & MeasurementMany types of force exist. Besides the four fundamental interactions (gravity, electromagnetism, weak & strong nuclear), there are numerous everyday forces that are human-scale manifestations of the fundamental interactions.

Laws vs. Definitions in Physics: Revelation vs. Convention (RP4a)

Sep 18, 2012   //   by Eric   //   Radical Physics, RPn  //  Comments Off

Laws vs. Definitions in Physics - Revelation vs. ConventionIt’s important to distinguish physical laws from definitions. DEFINITIONS have a local, human source; they are made by convention. However, in physics, LAWS come from the universe; they are revealed.

Force, Inertia, & Newton’s First Law of Motion (RP4)

Sep 18, 2012   //   by Tucker   //   Radical Physics, RPn  //  Comments Off

Force, Inertia, & Newton, surfThis 4th Radical Physics (RP) “taproot” episode clarifies the concept of force and properly introduces the Law of Inertia (aka Newton’s 1st Law of Motion).

Innumeracy, Part 1: Triple Powers of Ten (RP2c)

Sep 18, 2012   //   by Tucker   //   Radical Physics, RPn  //  Comments Off
Innumeracy, Part 1: Triple Powers of Ten
Innumeracy is the numerical equivalent of illiteracy: an inability to deal with numbers, particularly large numbers.  This Radical Physics (RP) tendril episode introduces a solution to the important social(!) problem of innumeracy.

Significant Figures & Scientific Notation (RP2b)

Sep 18, 2012   //   by Tucker   //   Radical Physics, RPn  //  Comments Off

Radical Physics: Significant Figures

Accuracy in measurement and calculation is crucial to science.

This Radical Physics (RP) tendril episode introduces scientific notation and “sig figs,” two important tools for maintaining and displaying accuracy.

 

Inertia, Mass, & a Bad Law of Physics – Newton’s 1st Law Clarified (RP3)

Apr 25, 2012   //   by Tucker   //   News in 2011, Radical Physics, RPn  //  1 Comment

This is the third taproot episode of Radical Physics. The “bad law of physics” in the title refers to a common misstatement of Newton’s first law of motion (N1).  Once inertia is properly understood, then the power, scope, and surprise of the real N1 can be appreciated.
