Physics Flashcards
He distinguished between the lodestone effect and static electricity produced by rubbing amber, which gave rise to the English words “electric” and “electricity.”

a piece of magnetite or other naturally magnetized mineral, able to be used as a magnet.
Lodestone

it refers to any contact with electricity, not just
human or animal contact.
“electrocution”
one of the largest energy consumers in the world.
A spark of static electricity can measure up to
3,000 volts.
is crucial for the heart’s function, as it
uses small electrical pulses to beat and pump
blood.
Electricity
- smallest amount of electric charge having the
characteristic called negative polarity
Electron
- Smallest amount of electric charge having the
characteristic called positive polarity
Protons
a renowned inventor, used
the torsion balance to measure the magnitudes of electric forces between charged objects.
Charles Coulomb
called a conductor of electricity.
These are materials that allow charges to move freely through them.

If the material does not transfer electricity they are
insulators.
if an atom has more or less electrons than protons, that atom acquires an (BLANK)
