|The so-called "standard model" of the the definition of force, in modern terms, of which four varieties of forces, strong nuclear force, electromagnetic force, weak nuclear force, and the gravitational force, are said to account for all movements in the universe, and in which the mechanism of the force is said to operate via the exchange of field particles, messenger particles, or force carriers which come in four varieties: gluons, photons, bosons, and gravitons, which carry and transmit the force. |
“Force is power acting by law in space in time.”
1. Strong nuclear force – mediates subatomic interactions.The forth of these, namely gravity, however, can be shown to but a version of the electromagnetic force; hence, it can be argued that there are only three fundamental forces of the universe, as things currently stand.
2. Electromagnetic force – mediates atomic and molecular interactions.
3. Weak nuclear force – mediates radioactive decay processes.
4. Gravitational force – mediates interactions between objects with mass.
See main: Exchange forceIn modern terms, forces are said to be mediated by particles or entities called "force carriers" or field particles. 
“Sometimes I think the force is stronger in the dead than in the living.”— Steve Berry (c.2000) (Ѻ) (Ѻ)
