	Free-fall - Wikipedia, the free encyclopedia
		More generally, free fall is the condition of acceleration due to gravity and air friction: in parachuting, free fall (skydiving) refers to the act of falling and delaying the opening of a parachute.
		Free fall in the strict sense is the condition of acceleration which is due only to gravity.
		It is estimated that a person free falling horizontally reaches a terminal velocity of around 120 mph (200 km/h) after a fall of just 1,000 ft (300 m), so the additional 19,000 ft (5,700 m) doesn't make these falls that much more dangerous, apart from the lack of oxygen at high altitude.

	Free Fall Associates - Wikipedia, the free encyclopedia
		Free Fall Associates was a computer game developer of the 1980s and early 1990s.
		After the disappointment of their later titles, Free Fall went on to develop some online card games which were featured on Prodigy's GameTV service.
		Both these games were lucrative for both Free Fall and EA and were key to EA's success as a fledgling publisher.

	Free Falling Object
		The remarkable observation that all free falling objects fall with the same acceleration was first proposed by Galileo, nearly 400 years ago.
		If the object falls through the atmosphere, there is an additional drag force acting on the object and the physics involved with the motion of the object is more complex.
		An object that falls through a vacuum is subjected to only one external force, the gravitational force, expressed as the weight of the object.

	The Free Fall Research Page: Unplanned Freefall? Some Survival Tips by David Carkeet
		The concept of "breaking the fall" is powerful, as is the hopeful message implicit in the nursery song "Rock-a-bye, Baby," which one must assume from the affect of the average singer tells the story not of a baby's death but of its survival.
		The redwood is attractive for the way it rises to shorten your fall, but a word of caution here: the redwood's lowest branches grow dangerously high from the ground; having gone 35,000 feet, you don't want the last 50 feet to ruin everything.
		For example, although you fall faster and faster for the first fifteen seconds or so, you soon reach "terminal velocity"—the point at which atmospheric drag resists gravity's acceleration in a perfect standoff.

	Galileo and Free Fall
		Now that you are familiar with the historical concepts of free fall, move on to the experiment.
		After Galileo defined uniform acceleration so that it would match the way he believed freely falling objects behaved, his next task was to devise a way of showing that the definition for uniform acceleration was useful for describing observed motions.
		Realizing that a direct quantitative test with a rapidly and freely falling body would not be accurate, Galileo proposed to make the test on an object that was moving less rapidly.

	Amusement Park Physics -- Free Fall
		A freely falling body is an object that is moving under the influence of gravity only.
		Just as Galileo and Newton explain in their theories of free fall, the least massive and most massive riders fall to the earth with the same rate of acceleration.
		His classic experiments led to the finding that all objects free fall at the same rate, regardless of their mass.

	* Dusted Reviews - Ken Vandermark's Free Fall *
		Free Fall, one of his latest divinations, is a trio coupling his clarinets with the Norwegians Swede Hårvard Wiik on piano and Ingebrigt Håker Flaten on double bass.
		Free counterpoint and an egalitarian approach to melody regularly enter their compositional equations.
		He makes it explicitly clear in his accompanying notes to Furnace that the trio is not intended to be a Jimmy Giuffre tribute band, but the instrumentation and approach belie a strong influence just the same.

		A simple rule to bear in mind is that all objects (regardless of their mass) experience the same acceleration when in a state of free fall.

		In the presence of air resistance, the elephant is sure to fall faster.

	Jeans mass - Wikipedia, the free encyclopedia
		Now, when the sound-crossing time is less than the free-fall time, pressure forces win, and the system bounces back to a stable equilibrium.
		However, when the free-fall time is less than the sound-crossing time, gravity wins, and the region undergoes gravitational collapse.
		At the same time, gravity will attempt to contract the system even further, and will do so on a free-fall time

		When objects fall through a medium such as air or water they accelerate until the effort required to move through the medium at a certain speed is great enough to match the weight of the object in the medium.
		Since the factor of time appears twice, multiplied by itself, then the distance traveled must be proportional to the second power of time, with a constant of proportion equal to one half of the acceleration, assuming the initial velocity was zero.
		The ratio of distance to time is the average velocity, which is exactly one half of the final velocity, in this case the speed at the bottom of the plane.
