The friction between two stationary forces is called static friction. It is the friction that resists two objects to start moving against each other. Once in motion, the friction between two forces is called dynamic friction. Static friction tends to be greater than dynamic friction, which is why it takes more force to get a heavy box moving along the ground compared to keep it going.
The friction on a rolling object is called "rolling friction" or "rolling resistance". It is caused by surface deformations, sliding, and adhesion.

The force that resists motion between objects that are in contact is called friction. One object can be stationary or they both can move.

The friction is static friction.
Static Friction
Kinetic friction is any friction between objects that are in contact and have relative motion. The specific term for objects that roll across other objects is aptly called rolling friction. Rolling friction exerts its force in the opposite direction of its motion.

Friction is caused when objects or substances bump into each other. When you swim you create friction between you and the water which is called Fluid friction. Better yet look it up
Its called Fluid Friction
