Because it just exists, we have no way of learning about it since you cant do anything to it.
Yes. The surface gravity on Mars is about 38% of what it is on Mars, a little more than twice the surface gravity on the moon, where people have stood and walked.
So far, the only body outside of earth that humans have ever stood on is the moon.On the moon, the force of gravity is about 1/6th of what it is on earth,so overcoming gravity was not a critical issue there.There is no known means of overcoming gravity, except to be prepared with well developed leg muscles.Within the solar system, the planets with greater gravitational force than on earth are the gas giants,with solid surfaces ... if they have any ... buried under hundreds or thousands of miles of radio-opaque,poisonous atmosphere. Astronauts are unlikely to be dispatched to land on them.
well it would difficult to the lack of gravity but under some instances you could do a summer salt on the moon.
No, an object with mass will always experience the gravitational force, so it cannot be truly weightless when under the influence of gravity. Weight is the measure of the force of gravity acting on an object, so as long as gravity is present, the object will have weight.
Weight them under gravity or calculate from momentum of impact or spring load under centripetal force in space. Then refer the weight or the force to the gravity of earth at 9.81m/s2 and account for its' weight under earth gravity.
Definitely. A rock sinks in the ocean because gravity operates on it even under water. A log floats in water not because gravity stops under water but because the log's density is lower than that of the water.
black holes are stars which collapsed under their own gravity.
It falls under water and the effect of gravity.
There's no gravity in outer space, so you would just float in one place.
Gravity is not well understood. It is a property of matter.
If the gravity is not constant over the body.
-- Vast hydrogen clouds shrink and compress under the influence of gravity to form stars. -- Tiny particles of dust, gas, and rock aggregate under the influence of gravity to form planets. -- Planets execute motion in closed orbits around stars under the influence of gravity. -- Strapless evening gowns stay up in consideration of the gravity of the situation that would ensue if they did not.
