physics Flashcards
gravitational
relating to movement toward a center of gravity.
radiant
Radiant energy is the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment.
chemical
Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.
thermal
Thermal energy refers to the energy contained within a system that is responsible for its temperature.
elastic
Elastic potential energy is energy stored as a result of applying a force to deform an elastic object.
nuclear
Nuclear energy is the energy in the nucleus, or core, of an atom
geothermal
Geothermal energy is heat within the earth.
sound
Sound energy is the result when a force, either sound or pressure, makes an object or substance vibrate.
mechanical
Mechanical energy is produced by sourcing potential and kinetic energy and turning it into power.
hydroelectric
is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity
series circuits
A series circuit comprises a path along which the whole current flows through each component.
parallel
A parallel circuit comprises branches so that the current divides and only part of it flows through any branch.
power source
A power source is a source of power. Most commonly the type of power referred to is: Power
connector
wire
load
obeject that recives the power
control
on and off switch
pulley
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
lever
a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.
wheel and axle
a simple lifting machine consisting of a rope which unwinds from a wheel on to a cylindrical drum or shaft joined to the wheel to provide mechanical advantage.
wedge
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.
inclined plane
a plane inclined at an angle to the horizontal.
a sloping ramp up which heavy loads can be raised by ropes or chains.
screw
a short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.
