## Kinetic Energy | Physics

Energy is available on earth in different forms. These forms are like kinetic energy, potential energy, electrical energy, heat energy etc. We know that a moving object can do work. An object which is moving faster does more work than an object moving relatively slow. Moving bullet, blowing wind, rotating wheel, a speeding stone all

## Climate Change Explained

This is a simple explanation of Climate Change, based on an article in the New York Times. The average temperature on the surface of the planet has already increased 1.7 degrees Fahrenheit since 1880, which may not seem like much, but think about it this way, the heat from human emissions is roughly equal to

## 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

## Work & Power in Physics (RP11)

The concept of WORK is very important in physics, and it’s important — and laborious! — in everyday life, too. But in physics, Work intimately connects to two deep ideas that Radical Physics has already explored: FORCE and ENERGY. You remember, I hope, that FORCE is just a push or pull. We defined it that

## What is Heat? A brief introduction at the particle level.

Let’s start with an illustration here we have hot and cold blocks of some material they each have a thermometer in them If we put them together, Let’s take a look! you can see that there has been a transfer of energy from the hot block to the cold block resulting in the same temperature

## Schrödinger equation 4: Probability density, Integration, and Units

[typing] Oh, better save. No. NO! [Slow motion] KHAAAAAAAAAAAAAAaaaaaaaaannnnn! [Epic sports music: “Eighties Action” by Kevin MacLeod, Royalty-free from incompetech.com] [Music: “Cephalopod” by Kevin MacLeod, Royalty-free from incompetech.com] This episode, we’re going to be discussing something I’ve been avoiding until now, but it’s the easiest way to explain the units of our wavefunction, even though

## Schrödinger equation 3: Complex conjugate, Phase rotation, and Energy

[Deep voice] QUANTUM ENERGY… [Normal voice] No, really. I just do that [Deep voice] WHEN I’M EXCITED… In hindsight, maybe I shouldn’t do that anymore. [Deep voice] HAPPY ST. PATRICK’S DAY… [Deep voice] HAPPY BIRTHDAY… [Noisemaker sound] Yeah… What were we talking about last episode? Something about orbiting planets? Ehn, let’s go with that. Suppose
