Crash Course Physics #26: Electric Fields
As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating and a crucial part of physics. In this video episode of Crash Course Physics, Shini chats about...

Khan Academy: Magnitude of Electric Field Created by a Charge
In this video, David from Khan Academy explains how to find the magnitude of the electric field created by a point charge and solves a few examples problems to find the electric field from point charges.

Khan Academy: Electric Field Direction
The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point. This video demonstrates how to solve electrical field problems. [12:35]

Khan Academy: Discovery of Magnetic Fields
Magnetic materials seem to have two sides (we could call them poles). Depending on orientation, they can be attractive or repulsive. What is the shape of the force between fields? [1:07]

Pbs Learning Media: Crash Course Chemistry: Real Gases
Hank explains how the constants in the gas law aren't all that constant. The ideal gas law has to be corrected for volume because atoms and molecules take up space and for pressure because they're attracted to each other. Einstein was...

Pbs Learning Media: Crash Course Physics: Thermodynamics
Have you ever heard of a Perpetual Motion Machine? More to the point, have you ever heard of why Perpetual Motion Machines are impossible? One of the reasons is because of the first law of thermodynamics! [9:53]

Pbs Learning Media: Crash Course Chemistry: Doing Solids
In which Hank blows our minds with the different kinds of Solids out there and talks about why they're all different and have different properties. Today, you'll learn about amorphous and crystalline solids, types of crystalline solids,...

Pbs Learning Media: Crash Course Chemistry: Calorimetry
Today's episode dives into the HOW of enthalpy. How we calculate it, and how we determine it experimentally...even if our determinations here at Crash Course Chemistry are somewhat shoddy. [11:55]

Pbs Learning Media: Crash Course Physics: Fluids at Rest
In this episode of Crash Course Physics, Shini is very excited to start talking about Fluids. You see, she's a Fluid Dynamicist and Mechanical Engineer, so fluids are really important to her. Actually they're really important to anyone...

Pbs Learning Media: Crash Course Physics: Newton's Laws
I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of...
PBS
Pbs Learning Media: Crash Course Chemistry: The Electron
Hank brings us the story of the electron. He describes how reality is a kind of music, discussing electron shells and orbitals, electron configurations, ionization and electron affinities, and how all these things can be understood via...
