## Radical Physics Intro – God’s Thoughts & the Awesome Machinery of Nature (RP1)

What ho! My name is Tucker Hiatt. I am a physics teacher with 35 years of experience, and I am also the executive director of Wonderfest, the San Francisco Bay Area Beacon of Science. Welcome to Radical Physics. What’s radical — besides our location here in the Gamma Sector of the Milky Way — I’ll

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

When asked to cite a very basic law of physics, many people reply with something that they might call “the law of inertia”: An object at rest tends to stay at rest; and an object in motion tends to stay in motion. This would-be law of physics suffers from some BIG problems: Its first half

## Forms of Energy: Kinetic, Thermal, & Potential (RP12)

Now we’re ready to use the physics definition of WORK to develop ideas about — and formulas for — some important FORMS of energy. By “forms of energy,” I don’t mean anything anthropocentric (like enthusiasm, or spirit). And I don’t mean anything BIOcentric (like a mysterious life energy, or the Chinese Qi). It turns out

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

Welcome back to Radical Physics. It’s time to learn our first official law of physics. This is exciting: the first law of physics! We might call it the first — and most basic — law of nature. No one knows why this law is true. And it took people a LONG time to realize that

## How to Convert Units of Measurement in Physics & Chemistry (RP6a)

EVERY physical variable (distance, time, mass, speed, energy, and so on) has units of measurement. For example, the agreed-upon international unit of speed (and of velocity) is the meter per second, abbreviated m over s. Sometimes international units are inconvenient. For example, if you happen to be speeding in the United States, you might need

## Velocity in Physics – Meaning, Measurement, & Calculation (RP6)

In RP2, we got a feel for the meaning of speed and velocity. Now is the time to define these little beasties more carefully. We’ll start by doing something weird: we’ll constrain movement to one dimension: that’s motion in a straight line, either forward or backward. If we can describe 1-dimensional motion, then maybe it

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

RP4 tells us a lot about force, IN GENERAL. Let’s briefly look at a few SPECIFIC forces. Many of these will be considered in detail in later episodes. We are all familiar with the force of gravity. On Earth, gravity gives things weight. It is a force (measured in newtons, as are ALL forces) that
