Acceleration is the rate of change of velocity. This seventh Radical Physics (RP) taproot episode gets at the heart of kinematics and lays the foundation for much of mechanics.
Measurement is crucial to science. And the ability to convert measurements from one set of units to another is crucial for science students! This Radical Physics (RP) tendril episode teaches how units conversion works.
Many 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.
It’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.
This 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).
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.
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.
Here is the Radical Physics Movie Action (RPMA) analysis of a scene from Mission: Impossible – Ghost Protocol, wherein an IMF agent survives a fall from a tall building. Check out the excite and the science of RPMA – Mission:Impossible IV – Crash Pad in a Can.
Here is the Radical Physics Movie Action (RPMA) analysis of a scene from Mission: Impossible – Ghost Protocol, wherein Tom Cruise falls 100 meters. Don’t miss the excitement and the science of RPMA – Mission:Impossible IV – 100-meter, 100-mph Drop.
Here is the Radical Physics Movie Action (RPMA) analysis of a scene from Mission: Impossible – Ghost Protocol, wherein Tom Cruise bails out of a speeding car. Don’t miss the excitement and insight of RPMA – Mission:Impossible IV – Freeway Bail-Out.
From the hallowed GP (“Good Physics”) rating to the dreaded NP-17 (“No Physics; no one under — or over — 17 should view”) designation, here is the Radical Physics Movie Action (RPMA) Rating System.
Astronomy expert Andrew Fraknoi explains the reasoning behind Pluto’s apparent demotion to “dwarf planet” status. This special Radical Physics (RP) episode is entitled RP Interview: Andrew Fraknoi on Pluto’s Exit from the Planet Club.
Astronomy expert Andrew Fraknoi explains the harrowing experience of someone who falls into a black hole. This special episode of Radical Physics (RP) is entitled RP Interview: Andrew Fraknoi on Falling Into a Black Hole.
Astronomy expert Andrew Fraknoi explains the exotic origins of every atom on Earth (except hydrogen). This special episode of Radical Physics (RP) is entitled RP Interview: Andrew Fraknoi on the Origins of Our Atoms.
This is a “tendril” episode of Radical Physics’s second taproot program. It explores the deep ambiguity of this seemingly simple question: How fast are you going?
The second taproot episode of Radical Physics is RP2 – Need for Speed: From Usain Bolt to Voyager. Here we explore speed, AND we lay a firm foundation for understanding relativity theory.
Here is a video “tendril” of RP1, the first Radical Physics taproot episode. RP1a – Deep Mysteries: Not Taking the World for Granted presents some of reality’s most profound mysteries. Brace yourself for an exploration — or at least a listing — of the great unknowns!
