Centripetal		A type of collision where momentum is conserved, but KE is not.
Elastic		The slope of a position-time graph, can be or -
Velocity		The rate of change of velocity with time
Potential		The product of force and distance when they act in the same direction
Energy		A push or pull on an object due to the interaction of two objects.
Work		A term used with "energy" or "friction" that implies motion
Speed		A term often used with "acceleration" that literally means "center-seeking"
Newtons		A force that exists between any two masses separated by a distance
Acceleration		A change in momentum
Gravity		A quantity with magnitude
Inertia		How fast an object is traveling
Impulse		The tendency for an object to resist changes in velocity; directly related to its mass.
Power		The type of force that is directed perpendicular to a surface
Force		The change in position of an object (from start to finish)
Displacement		The rate at which work is done; the rate at which energy is used.
Kinetic		A force that opposes motion when two surfaces slide past each other
Normal		Inertia in motion
Period		The size of a given quantity - how much? how fast? how far? etc.
Inelastic		A term used with "energy" that implies stored energy.
Static		The units for mass when using an equation
Vector		The number of circles or cycles per unit of time
Friction		A term used with "friction" that implies a lack of motion
Momentum		The amount of time for a complete circle or cycle
Frequency		A type of collision where both KE and momentum are conserved
Kilograms		The units used to measure force
Magnitude		The ability to do work
