It is a force that opposes motion between two surfaces sticking or touching together.

• friction

• air friction

• gravitational friction

• static friction

It affects the motion of falling objects by acting against the force of gravity.

• friction

• air friction

• gravitational friction

• static friction

It is also called dry friction, which occurs when two objects rub against each other or slide against each other.

• sliding friction

• air friction

• gravitational friction

• static friction

It is friction between moving objects and a fluid which can either be liquid or gas.

• sliding friction

• air friction

• fluid friction

• static friction

It occurs in stationary objects or objects at rest.
