Category 1
activity involving mental or physical effort done in order to achieve a purpose or result
Work
an apparatus using or applying mechanical power and having several parts, each with a definite function and together performing a particular task
Machine
the work done by a simple machine, compound machine, or any type of engine model
Work output
a position in a scale or rank
Level
simple machine consisting of a sloping surface, used for raising heavy bodies
Inclined plane
the SI unit of work or energy
Joule
the force with which you push or pull an object and the force that you would need to lift the object without the inclined plane
Input and Output Force
a measure of the ratio of output force to input force in a system
Mechanical advantage
the point on which a lever rests or is supported and on which it pivots
Fulcrum
a piece of wood, metal, or some other material having one thick end and tapering to a thin edge, that is driven between two objects or parts of an object to secure or separate them
Wedge
the ability to do something or act in a particular way, especially as a faculty or quality
Power
the distance over which the input force is applied
Input distance
the mechanical advantage determined by physical measurement of the input and output forces
Actual mechanical advantage
The side of a lever on which force is applied
Input arm
a nail-shaped or rod-shaped piece with a spiral groove and a slotted or recessed head designed to be inserted into material by rotating and used for fastening pieces of solid material together
Screw
the SI unit of power
Watt
The MACHINE does work by exerting a force over another distance
Output distance
the mechanical advantage of a perfect machine with no loss of useful work caused by friction between moving parts
the portion of the lever directly connected to the load
Output arm
a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used to raise heavy weights
Pulley
a unit of power equal to 550 foot-pounds per second
Horsepower
the amount of energy supplied to the machine
Work input
the state or quality of being efficient
Efficiency
Wheel and Axle
a machine made up of two or more simple machines working together
