The Strong Nuclear Force
Holds quarks together to form protons and neutrons.

Holds nucleons together in an atom to form a nucleus
Its force carrying particles are called gluonshttps://universe-review.ca/I15-02-residual.jpg (06/08/2015)

Automatic pull between two objects which have mass
Gravitational Force
We are lighter in the moon.

It has infinite range
