The First Law of Thermodynamics: Internal Energy, Heat, and Work
In chemistry we talked about the first law of thermodynamics as being the law of conservation of energy, and that's one way of looking at it, but physicists like doing math more than chemists do, so let's talk about the first law in...

The Laws of Thermodynamics, Entropy, and Gibbs Free Energy
We've all heard of the Laws of Thermodynamics, but what are they really? What the heck is entropy and what does it mean for the fate of the universe? How does soap work?! So many questions answered in this clip! Enjoy!

Understanding Mechanical Energy and the Conservation Principle
The video discusses the law of conservation of energy, focusing on mechanical energy, specifically gravitational potential energy. It explains how energy is transformed and transferred between different forms, such as kinetic and...
Professor Dave Explains
Internal Energy
We know about kinetic energy and potential energy, which can interchange when an object moves through a gravitational field, so let's add to that list the internal energy of the object. This gives us a new and comprehensive way to...

Kinetic Energy and Potential Energy
You can put energy into an object. Wanna know how? No, you don't need a Harry Potter wand. Just lift it up above your head! By doing so, you bestow the object with more potential energy. Learn more about the energy of motion and the...

Physics Girl: Is Energy Always Conserved?
When light passes through the universe and is redshifted by the expansion of space itself, how is energy conserved? The stretched light has a longer wavelength and therefore a lower energy. Is energy conserved? If so, where does it go?...
