idk a good name Flashcards
force
any of the various factors that cause a body to change its speed directon or shape
force field
a region or space in which a given effect such as magnetism exist
net force
a single force whose external effects on a rigid body are the same as the effects of sevarl actural forces acting on the same body
non contact force
forces that act between two objects that are not physically touching each other
atom
the smallest unit of a chemical element an atom consists of a dense central nuculus composed of protons and netrunas surrounded by a cloud of rapidly orbiting electrons
electron
a stable subatomic particle with a negative electric charge that is opposite to that proton but is equal in magnitude this is what gets transferred in electricity and static electricity
neutrons
an electricity neutral or no charge subatomic particles that has a mass slightly greater than that of a proton and its part of every atomic nucleus
proton
a stable subatomic particle that is part of the nucleus of an atom and has has a positive electric charge its charge is opposite to that of an electron but is equal in magnitude the amount of protons depends on the iduviual element
static electricity
electric charge that accumulates on an object rather than flowing through it as a current
magnetic
domain a region composed of a group of atoms whose magnetic field are aligned in the same direction
permanent magnet
a magnet that retains its magnetism after removal of the magnetizing force
pole
either of two areas of a magnet where the magnetic field is the strongest the north and south poles are the strongest
insulator
a material of such low conductivity that the flow of current through it is negligible usually ruber
conductor
a substans body or device that readily conducts heat electricity sound etc copper
eletric motor
an electric motor is a device for converting electricity enrgy into mechanical enrgy in the form of rotation
