Expert Answer:

Gravitational force: The force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface; "the more remote the body the less the gravity"; "the gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them";

Frictional force: The frictional force is a force exerted by a surface as an object moves across it or makes an effort to move across it.The friction force often opposes the motion of an object.

Frictional force is a contact force while gravitational force is a non-contact force.
