Gravitational potential energy is the energy an object has by virtue of its position above the surface of the Earth. When an object is lifted, work is done. When work is done in raising the height of ...

JONNY NELSON: Energy. There are lots of different types and lots of different ways of storing it. Chemical energy in a sparkler, elastic potential energy that fires a toy into the air, and many, many ...

The Work Energy Principle is one of the big ideas in introductory physics courses. It's so big that the textbook presentation can get a little confusing - but it doesn't have to be that way. I haven't ...

Nassim Haramein, Director of Research at the Hawaii Institute for Unified Physics (HIUP), has authored a paper titled “Quantum Gravity and the Holographic Mass,” which has been validated and published ...

Unfortunately for previous cosmological theories, the universe appears reasonably convincingly to be expanding at an accelerating rate. This, all physicists know, is no small problem. It is so severe ...

Let's file this post under "mistakes that Rhett made that he doesn't want to make again." If I don't write it down, I won't learn from my mistakes. How about I start this with the following problem.

According to Spectrum, several companies are poised to make a splash storing energy with gravity. That sounds fancy and high tech at first, but is it, really? Sure, we usually think of energy storage ...
