Because if you don't use it, then you lose it.
The muscles are used less without gravity, because floating around is possible. Astronauts need to exercise daily to keep their muscle mass the same.
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.
No force "acts on the force of gravity". Rather, both gravity and other forces - such as drag - will act on objects.
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.
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.
This is a very good question! You might be fooled into thinking that the only thing we feel if we walk around is the normal force pushing upwards against our feet, but this is because we are so used to feeling the effect of gravity (because it is almost never absent) that we are not consciously aware of it. You can check this by going into a rollercoaster or a fun fare attraction where there is a drop in free fall or even on a swing. In such situations you might feel a soft tingling in your stomach as your organs adjust to being in free fall. Being in free fall actually means you are no longer feeling the effects of gravity. This might sound strange, after all you are falling because of gravity! But it is true. In fact, it is the thing that prompted Albert Einstein to formulate his theory of gravity. And since we can feel the absence of gravity (the tingling of the stomach for example) we must also be able to feel gravity (or rather acceleration). It is just that we are so used to living with gravity and free fall situations are so rare that we think we do not feel 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.
It might cause the wheels to fall off.
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.
work out, dont eat fat food, and stay heathly
Exercising after eating could cause cramps.
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.
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
You might of pinched a nerve.
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.
Everything has gravity, the bigger it is the more it has. Moons DO have gravity, but it might be less than Earth's.
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
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.
