1 Unit 13: Particle Physics Four fundamental interactions in nature 1.Strong – responsible for binding neutrons and protons into nuclei 2.Electromagnetic -- about 10 -2 times the strength of the strong interaction and is responsible for the attraction of unlike charges and repulsion of like charges

2 Unit 13: Particle Physics Four fundamental interactions in nature 3.Weak – short range with strength of 10- 13 times that of strong interaction 4.Gravitational – holds planets, stars and galaxies together. The weakest of the four fundamental forces.
