Atom	This is the the most basic building block of matter and chemicals. It consists of a nucleus and electron shell.
Proton	A positively charged sub-atomic particle that resides within the nucleus.
Neutron	A sub-atomic particle that has no charge and resides within the nucleus.
Nucleus	The positively charged center of an atom which is made up of protons and neutrons and contains most of the atoms mass.
Electrons	Negatively charged sub atomic particles that make up the outermost shell of the atom and surround the nucleus.
Valence Electron	The last electron shell or energy level of an atom that determines its stability and cannot have more than 8 electrons.
Octet Rule	A rule that states that an atom with 8 Valence Electrons is stable.
Bohr Model
Matter	that which has mass and occupies space
Change of state	When an element, such as water, goes from one state (Gas, liquid, solid) to another. Examples of this include submilation, freezing, melting, condensation, and evaporation.
Submilation	The change of state from gas to solid or solid to gas. An example of this is dry ice.
Condensation	The change of state from gas to liquid.
Evaporation	The change of state from water to gas.
Freezing	The change of state from liquid to solid
Melting	The change of state from ice to liquid.
Distance	Which formula is this? D=m/v
Speed	Which formula is this? (r)=d/t
Acceleration	Which formula is this? v(f)-v(i)/t
Work	Which formula is this? w=fd
Power	Which formula is this? P=w/t
Motion	the act of changing location from one place to another
Speed	The distance traveled divided by the time interval which the motion occured.
Velocity	Speed of an object but only in one direction.
Acceleration	The rate at which velocity changes.
Force	A push or pull on an object that causes unbalanced forced resulting in the motion of an object.
Newton	The unit (N) which force is measured in.
Net Force	The total amount of forces combined in all directions on an object. Example- 1N west
Friction	The force opposing motion.
Gravity	The force of attraction between all masses in the universe.
Terminal Velocity	The greatest velocity a falling object reaches.
Free Fall	The motion of a falling object when the only force acting on it is gravity.
Projectile Motion	The curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth.
Inertia	An object will not move or stop unless an unbalenced force causes it to do so.
Momentum	The force or speed with which something moves.
Velocity	Which Formula is this? v=gt
Gravity	Which Formula is this? g=9.8 m/s2
Force	Which Formula is this? F=ma
Power	Which Formula is this? p=mv
Pressure	The measure of force per unit area.
Pascal	The unit in which pressure is measured also known as P and PA.
Atmospheric Pressure	The pressure caused by the weight of the atmosphere.
Density	The amount of matter in a certant space.
Pascal's Principle	When force is applied to a confined fluid, the change in pressure, is transmitted equally to all parts of the fluid.
Buoyant force	The upward force exerted by a fluid on a submerged object.
Archimedes' Principle	States that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces.
Bernoulli's Principle	As the velocity of a fluid increases, the pressure exerted by the fluid decreases.
Lift	The act of raising something.
Thrust	The act of applying force to propel something.
Drag	Pull, as against a resistance.
