From nuclear decay to gravity: the fundamental forces of our universe

In short: How do objects influence one another across a room or through direct contact? This video breaks down the four fundamental interactions that govern everything from radioactive decay to the orbits of planets.

Paul Andersen explores the mechanics of interaction, distinguishing between forces felt during physical touch and those acting at a distance. The core of these interactions lies in electromagnetic forces and fields, which explain both electrical behavior and gravity.

The presentation covers the specific roles of the strong and weak nuclear forces in causing radioactive decay. It also provides foundational physics context by detailing Newton's Law of Universal Gravitation and Coulomb's Law, while offering a structured teaching progression for K-12 education.
