what is velocity
the speed of something in a given direction.
newtons first law
A ball isn't going to move unless a certain object acts on it.
what is electricity.
a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
what is matter

what is chemistry
the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
what are bases
