Ch 12.4 Universal Forces

Part one of a four part series on the fundamental forces (or interactions) of physics begins with the strong force or strong interaction - which on the small scale holds quarks together to form protons, neutrons and other hadron particles.

Part two in the series on the four fundamental forces of physics by describing the weak interaction, which operates at an infinitesimally small scale to cause particle decay.

The Scishow continues their series on the four fundamental forces of physics with a description of gravitation -
the interaction by which physical bodies attract with a force proportional to that of their masses, and which is responsible for keeping planets in orbit, among other things.

In this final segment on the four fundamental forces of physics, The Scishow tackles the magnetic force, the second of the two ways in which electromagnetism is apparent in the universe.
