Because if you don't use it, then you lose it.

∙ 11y agoThe muscles are used less without gravity, because floating around is possible. Astronauts need to exercise daily to keep their muscle mass the same.

Is gravity dependent on density?
In general no, density is defined as the amount of mass per volume. However for materials on Earth it might indirectly, because gravity might cause additional pressure and thus increase the density. Consider air for example, the air pressure (and thus density) is higher here than 10 kilometers up because gravity pulls the air towards Earth.
What situations might drag act on the force of gravity?
No force "acts on the force of gravity". Rather, both gravity and other forces - such as drag - will act on objects.
Is gravity a attraction or repulsion?
In general gravity is an attractive force. There are some subtleties in general relativity however that might give the appearance of a repulsive force, but for almost all intents and purposes gravity is an attractive force.
Example of gravity related to mass?
Acceleration of gravity multiplied by mass gets you the weight of an object.The force of gravity on earth accelerates at 9.8m/s^2.Multiply the mass of the object (in Kg) by 9.8, and you will get the weight.Note:Mass of an object remains constant no matter where you are. Weight might not, because it is dependent on force of gravity.
Is it possible to maker anti-gravity water?
I don't know what you mean with "anti-gravity water". So far, nothing in the sense of "anti-gravity" has been achieved, and it doesn't seem reasonable to suppose it might be possible. For a start, anything that looks like "anti-gravity" would likely violate the principle of conservation of energy.
What might happen to an astronaut if she spent a long time on a plante wit less gravity?
If you were to spend a month in bed, your muscles would "atrophy" or weaken through lack of use. It would take time to regain your strength by exercising. Astronauts in space, or living for long periods on the Moon, Mars or Ganymede where gravity is lower, would weaken unless they exercised to keep their muscle tone. If you spend a year floating in zero-G for a year, you wouldn't be able to walk at all. Science fiction writers have speculated that humans born in space or on the Moon might never be able to come to Earth, because they would be unused to living in Earth-gravity. On the other hand, humans raised on high-gravity planets might develop very strong muscles just from having to stand up and walk, and might be champion weightlifters or athletes on Earth.
What will occur if a wheel is over tightened?
It might cause the wheels to fall off.
What is the fear of gravy called?
An irrational fear of gravity is called barophobia. Someone who has this phobia usually fear that they might be crushed by gravity, gravity might cease to exist or that gravity will cause them to fall.
What might cause muscles to get larger?
work out, dont eat fat food, and stay heathly
Exercising after eating can compromise oxygen and nutrient delivery to muscles. what might this cause?
Exercising after eating could cause cramps.
Why do hand muscles contract when vomiting?
Vomiting tends to make the body tense up. The hand muscles might contract as a result of this tensing. Also, vomiting can cause dehydration which can make muscles contract.
Is gravity a natural resource?
yes it is but you expend energy trying to use it-planetary gravity that is-universal gravity might be more usable be we are talking zero point technology-you get what you give/cause effect/dont get nothin for free
What would cause both of muscles in your arms to feel cold and being very sensitive to touch like your sheets at night?
You might of pinched a nerve.
Does The Sims 2 ruin your computer?
No. The sims 2 will not directly harm your PC but it might weaken your system and cause your PC to run slower but not for strong PC, running the game sometimes crashes your PC though.
Do all of the moons not have gravity?
Everything has gravity, the bigger it is the more it has. Moons DO have gravity, but it might be less than Earth's.
Why might someone with a cramp need to be given pure oxygen?
Muscle cramps result by build up of lactic acid in muscles that must go through anaerobic respiration when immediate energy required surpasses what the muscles can provide using aerobic respiration. Providing O2 drives aerobic reaction, providing O2 to the muscles and replacing lactic acid production. Increased delivery of O2 will weaken contractions causing cramps
Is smoking cause flu?
No, smoking cannot cause the flu. Flu is a virus. Cigarettes cannot spawn viruses. However, smoking can weaken your immune system and make you more likely to get sick. It also damages your lungs, so the flu might be more severe in a smoker.
