19. Fundamental Forces We have talked about a lot of different kinds of forces. Gravitational, friction, normal, fluid resistance, tension… Are these all actually different in nature? Four fundamental forces (we think): Gravitational Electromagnetic Strong Weak All interactions arise through one of these fundamental forces. All of the interactions we have dealt with so far were electromagnetic or gravitational.
