Air resistance: friction or drag that acts on something moving through air
Fluid: anything that flows; in particular, any liquid or gas
Inversely: when two values change in opposite directions, so that if one is doubled the other is reduced to one half, they are said to be inversely proportional to each other
Newtons second law: the acceleration produced by a net force on a body is is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the body
Pascal: the SI unit of pressure.
Pressure: force per surface area where the force is normal to the surface; measured in pascals
Terminal speed: the speed at which the acceleration of a falling object is zero because friction balances the weight
Terminal velocity: terminal speed together with the direction of motion.
