Static force also known as drag or air resistance is friction upon stationary objects. Kinetic or sliding force which acts on sliding objects. Rolling force which acts on rolling objects. Thanks to you answerers I didn't know this either so I learned something.

Static Friction, Kinetic Friction, and Rolling Friction.

sliding friction is when the surface of an object stays in contact with another surface, such as a sled moving on ice. rolling friction occurs when an object stays in contact with another object, but the same part of the surface is not always touching with that object. an example is a car driving down a street: its tire is rolling continuously. the third kind is fluid friction. this happens when an object moves through a gas or liquid. for example, a ship sailing through the ocean encounters fluid friction from the water (and to a lesser extent the wind).

Kinetic Force opposes velocity. Always less than static friction. Used for sliding objects.
Rolling Force opposes velocity. Used for objects that are rolling.
