From walking on the street to launching a rocket into space, physical forces are acting all around us. All the forces that we experience every day (and many that we don’t realize we experience) can be reduced to just four fundamental forces.
In order of decreasing strength, they are the strong atomic force, the electromagnetic force, the weak atomic force, and the gravitational force. These are the four fundamental forces in nature, and they govern everything that happens in the universe.
