A

astronomical Unit: The average distance from the Earth to the sun, about 150 million kilometers. AU Powerpoint

astronomy: The study of the moon, stars, and other objects in space.


B

buoyant force: The upward force exerted by a fluid on a submerged object.


C

chemistry: The study of the properties of matter and how matter changes.


D

density: density is the amount of material in a given unit of volume. D=m/v

 


E

electron: A tiny, negatively charge, high-energy particle that moves around the nucleus of an atom.


F

force: A push or a pull exerted on an object.


G

galaxy: A giant structure that contains hundreds of billions of stars. galaxy photos


H

heliocentric: A description of the solar system in which all of the planets revolve around the sun.

 

I

ion: An atom or group of atoms that has become electrically charged.


J

joule: A unit of work equal to one newton-meter.


K

kinetic energy: Energy that an object has due to its motion.


L

liquid: a state of matter that has no definate shape but has a definate volume.


M

Mass: Mass is the amount of material in an object. Mass can be determined using a balance. (triple beam balance) Mass =d x v


N

neutrons: small uncharged particles in the nucleus of an atom..


O

orbit: The path of an object as it revolves around another object in space.

T

tide: the rise and fall of water in the ocean. Tidal bulge PP video


U

umbra: the darkest part of a shadow, as in an eclipse.


V

Volume: Volume is the amount of space an object takes up. Volume can be determined using Length x Width x Height for a rectangular object, or by using the displacement method. (using a graduated cylinder) V=m/d


W

weight: A measure of the force of gravity on an object.


X

X-rays: electromagnetic waves with higher frequencies than ultraviolet rays, but shorter than gamma rays.


Y

y-axis: usually the axis on a graph where the responding variable is plotted.
