Forces of Nature Our understanding of the fundamental forces has evolved along with our growing knowledge of the particles of matter. Many everyday phenomena seemed to be governed by a long list of unique forces. Observations identified the gravitational, electric, and magnetic forces as distinct. A large step toward simplification come in the mid-19th century with Maxwell's unification of the electric and magnetic forces into a single electromagnetic force. Fifty years later come the recognition that the electromagnetic force also governed atoms. By the late 1800s, all commonly observed phenomena could be understood with only the electromagnetic and gravitational forces.
