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.

Bang on a drum and you create a disturbance. The drum’s vibrations set off a chain reaction: molecules move, air expands and is compressed, and a sound wave is born. It is straightforward to separate ...

We define and explain mathematically through multiple example problems. Segment 4E: Gravitational Potential and Kinetic Energy Gravitational potential energy and kinetic energy are defined and ...

In this beginner-friendly video, we explore the concept of gravitational potential energy. Learn how mass, height, and gravity work together to store energy and how this fundamental concept applies to ...

An apocalypse needs a lot or just a little energy—depending on what you compare it with. But what's really exciting is the math behind this ultimate destructive event. If you want to destroy Earth, ...
