in zero gravity, your muscles dont have to work very hard unless youre doing something. exercise for astronauts is important so that muscles dont become weak from not being used - also bones become weaker and less dense in zero gravity and nobody knows exactly why yet
An astronaut weighs less on the moon because the moon has less mass than Earth, meaning weaker gravitational force. Weight is the result of the gravitational force acting on an object's mass, so with less force on the moon, the astronaut feels lighter.
The moon is considerably smaller than the Earth, both in diameter and in mass, and it therefore has a much weaker gravitational field. The weight of an astronaut on the moon is the result of the mass of the astronaut, which is not changed by going to the moon, and the gravitation field of the moon. A weaker gravitational field produces a lower weight.
The ozone becomes weaker because of CFC's. They react and weaken CFC's.
it makes it weaker
One example is how light an astronaut weighed when standing on the moon. As there is very little gravity on the moon, the astronaut was able to jump much higher than he could back on earth.
Yes because every time you drink it, it makes your body weaker and weaker.
No asthma makes your lungs weaker-the worse your asthma the weaker your lungs.
