1 amp - ANS-It is equal to 120 watts
A ball is thrown with a force of 38N to a distance of 2.8 meters. How much work was created
through this action - ANS-89.5 Joules Force X Distance =
A vehicle turns sharply around a corner, creating a sideways force that is applied to the
passengers. What is this force known as - ANS-Centrifugal Force
AC and DC current - ANS-Alternating current and direct current
action and reactions - ANS-forces exist only in pairs
Airfoil - ANS-Shape of a wing, fan or propeller
Ampere - ANS-Measures electrical current
battery - ANS-two or more cells
buoyancy - ANS-the ability or tendency to float in water or air or some other fluid.
camber - ANS-When a surface is curved
Capacitive Reactance - ANS-A capacitor's opposition to the flow of current
capacitor - ANS-An electrical device used to store electrical charge.
Capacitor - ANS-Stores electric charge, easy pass AC but block DC
cell - ANS-supplies electrical current
components of force - ANS-The smaller the angle, the larger the effective force
conduit - ANS-metal, plastic or fiber tube used to protect and route electrical wiring in a building
or structure
conventional current - ANS-Current that flows from the positive side of the battery to the
negative side
Current = - ANS-Voltage (V) / Resistance (R)
Volts / Amperes
Diode - ANS-a device that allows the flow of electrical current in only one direction
dopants - ANS-chemicals that are applied to the silicon to determine whether it will act as an
insulator or as a conductor
Downwash - ANS-Airstream directed downward
drag - ANS-Resistance of the air (technically a fluid) against the forward movement of an
airplane.
effort - ANS-the force applied to a simple machine
effort distance - ANS-The distance over which the effort force acts in a simple machine.
elastic recoil - ANS-the tendency for the lungs to recoil or reduce in volume after being stretched
or expanded.
Equilibrium - ANS-net force is zero when velocity is not changing
fluid - ANS-Any substance that can flow
force - ANS-changes the velocity of an object
frequency - ANS-the number of times that alternating currents changes directions per second
friction - ANS-acts in opposition to motion, causes effort work to be larger than load work
fuse - ANS-Safety device that prevents electrical wires from overheating
