Hint: Force is mass contained in a body with an acceleration performed by the body. Forces available in nature are gravitational force, weak and strong nuclear forces and electromagnetic forces.

Complete step by step answer:
Gravitational force: Gravity is the force that pulls us to the surface of the earth, keeps the planets in orbit around the sun and causes the formation of planets, stars and galaxies.

Electromagnetism: Electromagnetism is the force responsible for the way matter generates and responds to electricity and magnetism.

Next come the less familiar forces, which are weak and strong nuclear forces, inside the nuclei of atoms. The strong nuclear forces bind the nucleus of an atom together. The weak forces are responsible for certain kinds of radioactive decay.

All the four forces do not interact together because all the forces are different and have no link with each other. All the four forces act at different fields and have different exchange of particles to act upon.

Note: Gravitational force is the one due to which we are bound to be attracted towards earth, gravitational force has let the planets to move in the orbits around the sun. Electromagnetic force too has many applications; all the electrical appliances work due to electromagnetic force existing in nature. Similarly, strong and weak nuclear forces are available in each atom or cellular structure of which we all or say living creatures are made up of.
