Surface forces have been used to provide defense zones around naval and merchant ship formations, air to furnish area surveillance, and mines for protection of limited areas.

Surface tension can vary because of inhomogeneous composition of the substances, and / or the temperature-dependence of surface tension forces.

* Surface combatant-large, heavily armed surface ships which are designed primarily to engage enemy forces on the high seas, including various types of battleship, battlecruiser, cruiser, destroyer, and frigate.

Surface tension is therefore measured in forces per unit length.

* Surface forces apparatus, a scientific instrument and technique

Surface friction forces the surface wind to slow and turn near the surface of the Earth, blowing directly towards the low pressure, when compared to the winds in the nearly frictionless flow well above the Earth's surface.

Surface tension is responsible for approximately 2 / 3 of the elastic recoil forces.

Surface tension exists because the molecules inside a liquid experience roughly equal cohesive forces in all directions, but molecules at the surface experience larger attractive forces toward the liquid than toward gas

Surface tension forces also draw fluid from capillaries to the alveolar spaces.

* Surface area available for contact between the reactants, in particular solid ones in heterogeneous systems.

The close of Surface Detail suggests that she remains in contact with Zakalwe long after the events of Use of Weapons.

Surface scientists use a goniometer to measure contact angle and surface energy.

Surface energy is most commonly quantified using a contact angle goniometer and a number of different methods.

Surface scientists use a contact angle goniometer to measure contact angle, surface energy and surface tension.

Surface scientists use a goniometer / tensiometer to measure contact angle, surface tension, and interfacial tension.

* Surface cavities ( or small holes ) can create a favourable geometric situation for the oil to withhold a protective lubrication thickness in the contact zone.

Surface representations can be expressed as the result of rules acting on the features of the underlying representation.

Surface processes comprise the action of water, wind, ice, fire, and living things on the surface of the Earth, along with chemical reactions that form soils and alter material properties, the stability and rate of change of topography under the force of gravity, and other factors, such as ( in the very recent past ) human alteration of the landscape.

Surface tension is a contractive tendency of the surface of a liquid that allows it to resist an external force.

Surface tension has the dimension of force per unit length, or of energy per unit area.

Surface tension, represented by the symbol γ is defined as the force along a line of unit length, where the force is parallel to the surface but perpendicular to the line.

Surface tension is the driving force for this movement.

Surface gravity, the force that holds down an atmosphere, differs significantly among the planets.

* Surface force apparatus

Surface tension quantifies the cohesive force present at the surface of a droplet.

* Surface textures that require low force to traverse on level, less than 5 pounds force per 120 pounds rolling force

In the Culture novel ( Surface Detail ) Veppers is informed that a single large GSV would be able to combat a fleet of 230, 000, 000 simple warships-representative of the combined force of an entire lesser civilisation-alone.

Surface Bond – Measures the force required to delaminate or split away the surface of laminate flooring plank or tile.

The BRO consists of the General Reserve Engineer Force ( GREF )— the execution force — under the Ministry of Surface Transport, and officers from Indian Army Corps of Engineers, who are deputed on loan to this organisation.

( This section may not have much force of law, as railroad operations, even those where a railroad physically exists in only one state, are governed by the Surface Transportation Board, a federal agency.

* Surface force

Surface topography is analyzed by the use of scanning force microscopy.

Surface water salinity ranges from 32 to 37 parts per 1000, the highest occurring in the Arabian Sea and in a belt between southern Africa and south-western Australia.

* Surface feet per minute, a unit of velocity used in machining to identify the machinability ratings of a material

Surface pressure forecasts are issued three times per day, with temperature and probability of precipitation products issued twice per day, using guidance from the NWS medium range forecast model ( GFS ) as well as models from the European Centre for Medium Range Weather Forecasting ( ECMWF ), the United Kingdom's Meteorology Office ( UKMET ), Canadian model, the Navy NOGAPS model, and ensemble guidance from the GFS, ECMWF, Canadian, and North American Ensemble Forecast System ( NAEFS ).

Surface brightnesses are usually quoted in magnitudes per square arcsecond.

This allowed it to have a speed limit higher than the National Maximum Speed Limit of, as per the Surface Transportation and Uniform Relocation Assistance Act of 1987.

Surface gravity is measured in units of acceleration, which, in the SI system, are meters per second squared.

Bodin Leir located near the air station is an RNoAF recruit school including Norwegian Advanced Surface to Air Missile System personnel and a national response unit.

Surface energy is conventionally defined as the work that is required to build a unit area of a particular surface.

Surface normals are three dimensional vectors of unit length.
