What is heat?

A transfer of energy:molecular motion

http://www.rpdp.net/sciencetips_v3/P8A1.htm

A sound’s pitch is determined by…

…the number of vibrations per

second.

This is a negative (-)

charged particle.

An electron

An electric current is…

A flow of electrons

A build up of electrons in one

location is called…

Static charge.

When an electric current travels along an unintended path

it is called…

A short circuit Ooops!
