Fundamental interaction

Fundamental interaction

Fundamental interaction which is also known as fundamental force in universe is four types of existence. Among four types of fundamental interaction two types are found its effect in long distance and visible in our daily life. These two fundamental interaction in gravitational force and electromagnetic force. Another two fundamental interaction, weak force and strong force is found in small scale distance. For example interaction in subatomic particles, strong nuclear interaction.

Fundamental interactions can be describe mathematically as field. For example, gravitational force is a fundamental interaction can be describe as spacetime curvature in General theory of relativity by Albert Einstein. Rest of three fundamental interactions are descrete quantum fields. These fundamental interaction is mediated by elementary particles described by standard model.
