Qtr. 2 Wk. 4: Work

TermDefinition
work force exerted on an object causing the object to move in the same direction as the force; work = force x distance
power the rate at which work is done; power = work divided by time
joule the SI unit of work; equal to one newton-meter
machine a device that makes work easier by changing the amount of force exerted, the distance over which a force is exerted, or the direction in which a force is exerted
simple machine one of six basic mechanisms that use mechanical advantage to multiply force
input force the force exerted on a machine by YOU
input work the input force times the input distance
output force the force exerted on an object by the MACHINE
output work the output force times the output distance
mechanical advantage the number of times a machine increases the force exerted on it; MA = output force divided by input force
