|
energy
|
the ability to cause change in matter
|
|
|
Kinetic energy
|
energy in motion
|
|
|
potential energy
|
stored energy/ the energy an object has because of its position
|
|
|
Law of Conservation of Energy
|
energy can not be created or destroyed
|
|
|
transformation of energy
|
changing from kinetic energy to potential energy and back
|
|
|
mechanical energy (also kinetic energy)
|
energy that moving objects have spinning top, flying airplane, rolling bicycle
|
|
|
electric energy (also kinetic energy)
|
energy caused by the movement of electrons
|
|
|
Chemical energy (also potential energy)
|
example plants absorb light energy from the sun to make food
|
|
|
electric charge
|
when an object gains or loses electrons ex. shocking each other
|
|
|
electric force
|
like objects repel (move away) opposite charges attract
|
|
|
electric current
|
flow of electrons
|
|
|
conductors
|
matter that carry electrons easily (wire, copper, metals)
|
|
|
insulator
|
a material that doesn't carry electrons (rubber, plastic, air)
|
|
|
resistors
|
resist the flow electrons in some ways (ex. filament in a light bulb)
|
|
|
series circuit
|
one path for the electrons (one bulb burns out, they all go out)
|
|
|
parallel circuit
|
separate paths (one bulb goes out, the rest stay on)
|
