Where would you be weightless?

Answer 1

Free fall is when the only forces acting upon an object is gravity. (There is no air resistance.) Weightlessness is when there is no gravity acting upon an object. (Weight is a measurement gravity.)

Answer 2

In skydiving freefall, you DO NOT feel weightless. When you leave the airplane, it is traveling at about 100 mph, so you are decelerating, in ten seconds you are at terminal velocity, about 120 mph. So you never experience an acceleration that would allow you to feel "that stomach thing". The big exceptions to this are jumping off something that is not moving (much) such as a balloon, antenna tower, cliff, bridge, or building. There you get several seconds of "weightless" feeling.

Answer 3

The Earth's gravity diminishes but acts over an infinite distance . There is nothing about being in "space" that brings about weightlessness.

The "weightlessness" that is talked about during an orbit means merely that the centripetal force imparted by the curved orbit cancels the effect of the Earth's gravity. Orbits are deliberately established this way so that minimum fuel is burned for the spacecraft to maintain position. At an altitude of 200 km (that's twice the distance above the Earth of where it is said space begins) the effect of gravity is only 6% less than on the surface of the Earth. Speed, altitude, and gravity must be precisely matched in order to maintain the equilibrium.

Answer 4

When there is no gravity.

Weight is the affect of gravity on a object. Objects in orbit or objects that are falling still have weight. In fact, and object in orbit around the Earth is in essence falling the entire time, but it never hits the ground because while it falls, the Earth is curving away beneath it.

There is no spot in space with no gravity, but there are spots where the gravitational forces cancel each other out. This is where an object can be weightless. (For example, if you were between the moon and the Earth, and both were pulling on you with the same gravitational force.)

Answer 5

Free fall occurs when a body is accelerating and moving in a direction perpendicular to the surface of the ground with no outside force acting on it other then the Gravitational pull. The acceleration here is a constant and that is, 9.8 ms-2
