gravitational force is an extremely feeble force. It is the weakest of the four fundamental forces. So it takes an astronomically huge object for us to start noticing gravity's effects with our bare eyes.
• The electromagnetic force causes electric and magnetic effects. it is the second strongest force .It can be attractive or repulsive, and acts only between pieces of matter carrying electrical charge.
Strong force is the force that holds together the nucleus of the atom, it is also known for the force that brings the smallest known particle together to form neutrons and protons.
• The weak force is responsible for radioactive decay and neutrino interactions. It has a very short range and week.
