Vector: A straight line drawn to scale that shows magnitude and direction of a force.
Vessel: Includes every description of watercraft used or capable of being used as a means of
transportation on the water.
Veterinarian: See Doctor of Veterinary Medicine.
Viscosity: The measure of a fluids resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of “thickness”; for example, honey has a much higher viscosity than water.
Viscous: Resistant to flow under stress.
Visual Infrared Thermometer: An instrument that measures the average apparent surface temperature of an object based upon the object’s radiance while providing either a visible light image or low-resolution thermal image on the instrument’s display screen.
Void: (1) An open space or break in consistency. (2) Air or gas that has been trapped and cured in a laminate during the manufacturing process.
Volt: Measure of potential energy. One volt is equal to1 joule per coulomb. Volt =joule/coulomb.
Voltage Drop: The difference between the source voltage and the voltage across a load supplied by the
source.
Voltmeter: Measures in volts the potential difference between two points in an electric circuit. Electric pressure or voltage is measure utilizing the voltmeter.
