An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. Each contact is a piece of electrically conductive material, typically metal.
A contact force is any force that occurs as a result of two objects making contact with each other. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter.
Electrical contact resistance (ECR, or simply contact resistance) is resistance to the flow of electric current caused by incomplete contact of the surfaces through which the current is flowing, and by films or oxide layers on the contacting surfaces.
The contact angle depends upon the medium above the free surface of the liquid, and the nature of the liquid and solid in contact. It is independent of the inclination of solid to the liquid surface. It changes with surface tension and hence with the temperature and purity of the liquid.

Eye contact. Two figures making eye contact in Caravaggio 's The Fortune Teller. Two students locking eyes. Eye contact occurs when two people or animals look at each other's eyes at the same time. [1] In people, eye contact is a form of nonverbal communication and can have a large influence on social behavior.
An ohmic contact is a non-rectifying electrical junction: a junction between two conductors that has a linear current–voltage (I–V) curve as with Ohm's law. Low-resistance ohmic contacts are used to allow charge to flow easily in both directions between the two conductors, without blocking due to rectification or excess power dissipation ...
Language contact. Language contact occurs when speakers of two or more languages or varieties interact with and influence each other. The study of language contact is called contact linguistics. Language contact can occur at language borders, [1] between adstratum languages, or as the result of migration, with an intrusive language acting as ...
Family law. In family law, contact, visitation and access are synonym terms that denotes the time that a child spends with the noncustodial parent, according to an agreed or court specified parenting schedule. [1] [2] The visitation term is not used in a shared parenting arrangement where both parents have joint physical custody.
Contact lenses, or simply contacts, are thin lenses placed directly on the surface of the eyes. Contact lenses are ocular prosthetic devices used by over 150 million people worldwide, and they can be worn to correct vision or for cosmetic or therapeutic reasons.
