Force Motion and Energy Flashcards
battery
a device that makes electricity by using chemical reactions
closed circuit
an electrical circuit that provides for a continuous path for current
complete circuit
closed curcuit
conductor
a material or object that allows electricity or heat to move through it
electrical circuit
the path along which electrons can flow
electrical current
the flow of electrons from negatively charged objects to positively charged objects
electrical energy
a form of energy resulting from the flow of electric charge
electricity
a form of energy that can be carried by wires and is used for heating and lighting, and to provide power for machines
energy
the ability to make something move or change
insulator
a material that allows little or no heat, electricity, or sound to go into or out of something
open circuit
an electrical circuit that is broken and carries no current
path
a course along which something travels
switch
a device that opens and closes an electrical circuit
force
a push or a pull
friction
the action of one surface or object rubbing against another
gravity
a force that pulls two objects toward each other
magnetism
the force of attraction or repulsion between substances made of certain materials, such as iron, nickel, cobalt, and steel.
motion/movement
an act or process of moving
position
the place where someone or something is in relation to other people or things
pull
to use force to bring something nearer to oneself
push
to use pressure against something in order to move it
repel
to force something to move away
electircal energy
a form of energy resulting from the flow of electric charge
energy
the ability to make something move or change
light energy
a form of energy which our sense of sight can detect. It is made of electromagnetic radiation and travels in a straight path
mechanical energy
energy in an object due to its motion or position, or both
sound energy
the movement of energy through a substance – like air or water – and is caused by vibrations
thermal energy
energy that comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature
lens
a piece of glass or other see-through material that is curved on one or both sides
light energy
a form of energy which our sense of sight can detect. It is made of electromagnetic radiation and travels in a straight path
medium
Material that light can be absorbed, reflect, or refracted
prism
piece of glass or other see-through material that has several flat sides, called faces. Has the ability to bend light
reflection
the bouncing back of a light rays from a smooth shinny surface
refraction
the bending of light rays as they move from one materiel into another material ,in water, lenses, prism, rainbow
transmit
pass through
thermal energy
energy that comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature
Rube Goldberg
a machine that uses a chain reaction to carry out a simple task. It performs a very basic job in a complicated way.
