Physical Science

screw a simple machine that consists of an inclined plane wrapped around a cylinder
pulley a simple machine that consists of a wheel over which a rope, chain, or wire passes
lever a simple machine that consists of a bar that pivots at a fixed pint
wedge a simple machine that is made up of two inclined planes and that moves; often used for cutting
work the transfer of energy to an object by using a force that causes the object to move in the direction of the force
inclined plane a simple machine that is straight, slanted surface, which facilitates the raising of loads; a ramp
wheel and axle a simple machine consisting of two circular objects of different sizes; the wheel is the larger of the two circular objects
simple machine a simple device for altering the magnitude or direction of a force. The six basic types are the lever, wheel and axle, pulley, screw, wedge, and inclined plane
force a push or pull exerted on an object in order to change the motion of the object; force has size and direction
pivot the central point, pin, or shaft on which a mechanism turns or oscillates.
power the rate at which work is done or energy is transormed
effort an exertion of strength or power, whether physical or mental, in performing an act or aiming at an object
fulcrum is a pivot point around which a lever turns, or something that plays a central role in or is in the center of a situation or activity
fixed point a reproducible invariant temperature; the boiling point, freezing point, or triple point of a substance, such as water, that is used to calibrate a thermometer or define a temperature scale
complex machine is a machine made up of two or more simple machines. Example: car
mechanical advantage The ratio of the output force (acting on a load) produced by a machine to the applied effort (the input force).
