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.

∙ 12y agoThe 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!

∙ 13y agofalling objects can't fall without gravity, so that is the same thing

∙ 13y ago-- 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

Who is better ermac or sub zero?
Ermac, because he can fly,teleport and move objects.
What keeps the planets and other solar system objects in orbit around the sun?
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 what would earth be like?
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!
How do large flocks or groups of flying animals like bats swallows starlings cranes etc fly en mass with out crashing into each other?
they have a sound wave and can direct themself around objects.
Have humans or human-made objects traveled to by or on Pluto?
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.
How do Unidentified Flying Objects fly?
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.
Why does Bernoulli's principle allow objects to fly?
people like to fly airplanes
Do object fly faster or slower in winter?
The objects fly slower during the winter.
Why must objects be grounded?
Objects must be grounded so that they do not fly around. If objects flew around they could break other objects or hurt people.
What are the objects name that fly in the air?
airplanes aircrafts? what do you mean?
How does the force of gravity affect the object?
The force of gravity attracts objects to the centre of the earth. It does not let objects fly out of its pull.
Does friction cause objects to move faster or fly higher?
false
Do all objects fall to the ground?
Yes unless you are in space or the object can fly
How hard the objects are what altogether?
unicorns cant fly but they can walk one rainbows
How do bats fly without knocking in the objects?
The use sound to detect what is around them. The echolocation sound bounces off objects and then back to the bat.
Why doesn't ore fly in straight lines?
b.The gravity of the other objects attracts them
Who is better ermac or sub zero?
Ermac, because he can fly,teleport and move objects.
