Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces. A force is a push or a pull that acts on an object due to the interaction with another object.

Many other experiments, including recent work with polymer thin films, generally confirm the existence of a non-contact friction force between surfaces separated by very small distances.
