# There are four fundamental interactions/forces in nature

Gravitation, electromagnetism, strong-nuclear, and weak nuclear. All phenomena are due to the presence of one or more of these interactions. Forces act on objects and can act at a distance through a respective physical field causing a change in motion or in the state of matter.
