Question	Answer
acceleration	The rate at which velocity increases in a given amount of time.
action-at-a-distance forces	Forces that act on an object without touching it.
action-reaction principle	For every action there is an equal and opposite reaction.
average speed	Realistically vehicles speed is not constant, so this is what
displacement	A change in position of an object.
dynamics	The branch of mechanics that describes why things move.
frame of reference	A system of reference points from which the position and motion of an object can be determined.
geostationary orbit	An object in the sky is orbiting at the same period as the surface of the earth below it so it seems to be stationary.
gravity (g)	The attraction that any object in the universe has toward other objects in the universe.
inertia	The property of matter that causes objects to resist change in the state of motion.
kinematics	The branch of mechanics that describes how things move.
magnitude	how big
mechanics	The study of motion.
newton (N)	The metric unit of weight.
satellites	Celestial bodies in orbit around another celestial body.
scalars	Quantities that express magnitude only.
speed	The rate at which an object changes position.
terminal velocity	The limit of the velocity at which an object can fall through a gas or a liquid.
Universal Law of Gravitation	This law created by Newton states that the force of gravity is directly related to the product of the masses of the two bodies and inversely related to the relative distance between the objects squared. F=G((m1*m2)/D squared)
vectors	Quantities that express magnitude and direction.
velocity	The rate at which an object changes position in a specified direction.
weight	The measure of the force of gravity on an object.
