Objects are in "freefall" when the only force on them is gravity (or none at all). When you stand on the ground there are two forces on you; gravity pulling down and the ground pushing up. When a satellite is put into orbit the engines give it a sideways boost then turn off. If Earth's gravity were not there it would move along that sideways direction and fly off into space. But gravity is there and pulls it down as it also moves sideways, so its in "freefall" . Since the Earth is a sphere the ground curves away faster then the satellite drops so it makes an orbit. Now everything on the satellite is in freefall exactly the same. So if you were standing on the satellite its surface would not push up on you (like the ground does on earth) because you and the satellite are both falling together. Also if you dropped your keys they would just hang there in front of you because they would fall exactly as you are falling. This all gives the sense of weightlessness.
The impression of "weight" is the RESISTANCE to gravity; if you are falling freely under the influence of gravity, you're not resisting it. So satellites in space, or objects INSIDE satellites in space, are in "free-fall" - they are not resisting gravity. So you feel weightless.
If you go snorkeling or Scuba diving, you are floating, your body is supported by your buoyancy in the water. You aren't resisting gravity; the water does that for you. So you feel weightless in the water. Which is one of the reasons why NASA trains astronauts in Swimming Pools!
I think that the answer is: ----- :)
Wind resistance?
Hot air Balloons, Kites, Parachutes, birds, air planes, hang gliders, gliders (plane type) etc.
falling objects can't fall without gravity, so that is the same thing
-- its acceleration is constant
-- its speed is proportional to the length of time it falls
-- the distance it falls is proportional to the square of the time it falls
The pull of the Earth is called "Gravity"
Ermac, because he can fly,teleport and move objects.
The force of gravity is what keeps planets and other objects in orbit around the sun, along with the angular momentum of the planets and objects. Without gravity, they would just fly away into space, and without angular momentum, they would just fall into the sun. But both of those together produce orbital motion.
If objects had no weight (ie if there was no gravity), then the Earth would not have formed in the first place. Neither would the Sun, or the Galaxies. On the other hand, if Earth's gravity suddenly disappeared tomorrow, then we (and anything not stuck down - including the atmosphere) would just fly off into space!
they have a sound wave and can direct themself around objects.
Not yet. The New Horizons space probe, launched in 2006, will fly by Pluto in June 2015. Humans themselves have only been as far as the moon.
Unidentified Flying Objects are objects which we are, by definition, unable to identify, and thus we will have no idea as to how they are able to fly.
people like to fly airplanes
The objects fly slower during the winter.
Objects must be grounded so that they do not fly around. If objects flew around they could break other objects or hurt people.
airplanes aircrafts? what do you mean?
The force of gravity attracts objects to the centre of the earth. It does not let objects fly out of its pull.
false
unicorns cant fly but they can walk one rainbows
Yes unless you are in space or the object can fly
The use sound to detect what is around them. The echolocation sound bounces off objects and then back to the bat.
they have less mass. heavier objects have a great mass so it gets pulled down faster..... by a little thing called......gravity!
b.The gravity of the other objects attracts them
