science magnet Flashcards
energy
motion or interaction of molecules, the ability to do work.
electron
subatomic particle that has a negative charge.
magnetism
a force that can attract or repel objects that contain a magnetic material inside of them
-caused by electrical charges
-magnetic materials: cobalt, nickel, iron, magnetite
magnetic field
a region around a magnetic material where the force of magnetism acts
*flow from positive to negative
charges
a physical property that causes matter to experience a force
-protons are positively charged
-electrons are negatively charged
attraction
being drawn to another object
*opposite charges attract
repel
to push away from something
*same charges repel
electricity
energy resulting from charged particles
static electricity
an imbalance of electric charges within a material
electric field
the area around an electric charge the experiences an electric force
-flow from positive to negative
electric current
when electric charges move
open circuit
a path that electricity flows along that is interrupted or disconnected
closed circuit
a complete path of electrical connection around which a current flows or circulates
series circuit
One path through which electricity flows
parallel
Multiple paths for electricity to flow from one point to another
