Fundamental Interactions

 These are the most basic interactions in physical systems. There are four conventionally accepted fundamental interactions: Gravitational, Electromagnetic, Strong force, and Weak force.

Garvitational Interaction

 This is the Interaction that a planet or some other large body that has it's own gravitational field can exert on the System from the Surroundings. The Gravitational Interaction from the Earth onto an object that is within Earth's gravitational field is 9.81 meters per second squared (m/s^2).

Electromagnetic Interaction

 This is the Interaction that charged particles can exert on the System from the Surroundings. Here we use Coulomb's Constant (8.98*10^9 n/m^2 (newtons*meters squared)) to describe the Interaction between electrically charged particles.

Strong Force

 This is the Interaction between subatomic particles of matter. The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atomic nucleus.

Weak force

 This is the Interaction that governs the decay of unstable subatomic particles such as mesons. It also initiates the nuclear fusion reaction that fuels the Sun.
