The difference in potential energy between two electrical points.
The rate of flow of electrical charges (electrons).
The basic unit of electrical current. This is equal to 1 coulomb of electrons flowing past a given point in 1 second.
Opposition to current flow.
The unit of electrical resistance.
Force times distance.
The capacity to do work; the property of a system that diminishes when the system does work on any other system, by an about equal to the work so done.
The rate of doing work.
The unit of electrical power. The power expended when 1 ampere of current flows through a 1 ohm resistance.
The exertion of force upon a surface by an object, fluid, etc., in contact with it.
The energy of a body or a system with respect to the motion of the body or of the particles in the system.
The energy of a body or a system with respect to the position of the body or of arrangement of the particles of the system.
Energy in a mechanical form.
The property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force..
An influence on a body or system, producing or tending to produce a change in movement or in shape or other effects. Force equals masss X acceleration.
Also called linear momentum. A quantity expressing the motion of a body or system, equal to the product of the mass of a body and its velocity.
The law that an external pressure applied to a fluid in a closed vessel is uniformly transmitted through the fluid.
A substance, as a liquid or gas, that is capable of flowing and that changes its shape at a steady rate when acted upon by a force tending to change its shape.
the state of matter in which a substance exhibits a characteristic readiness to flow with little or no tendency to disperse and relatively high incompressibility.
A substance possesing perfect molecular mobility and the property of indefinate expansion, as opposed to a solid or liquid. Highly compressible too unlike a liquid.
The time rate of change of velocity with respect to magnitude or direction; the derivative of velocity with respect to time.
The measure of the quantity of matter that a body or an object contains. The mass of the body is not dependent on gravity and therefore is different from but proportional to its weight.
A screw with a smooth shank and tapered point for use in wood.
A screw with threads for use with a nut or tapped hole. Ex. 8-32 for round light boxes and a 6-32 to attach devices such as receptacle to square electrical boxes.
Sheet Metal Screw
A fully threaded screw with a point for use in sheet metal. abbreviated SL.
Self Drilling SMS
A sheet metal screw with a self drilling point.
