Question

2. Space does not have gravitational force, so how do you think astronauts survive there? How do they eat
and sleep in space? Does moon have gravitational force? What is the difference between Moon and Earth
in terms of force?​

Answer 1

Answer:

look in explanation.

Explanation:

It is a somewhat misconception that space does not have gravitational force.

we do know there is gravitational force in space due to the presence and detection of gravitational waves. this is evident since we use them to detect black holes and other large objects.

as to the survival of astronauts, we technically do not require gravitation to survive in a largely general scale, still the lack of proper gravity is felt in the fact that the astronauts lose some of their muscle and bone density in space where the existing gravity is not felt.

also Eating and drinking in zero gravity presents out of this world problems.

Plates, bowls and cups are all out of the question as the food or drink will simply float away.

freeze dried galactic grub after the space explorers complained about the cuisine.

To make most freeze-dried foods, astronauts squeeze water into the food packages and then eat the food after it absorbs the water. Astronauts can use hot water to make hot meals

Some freeze-dried foods, like fruit, can be eaten dry and are in fact found in many terrestrial breakfast cereals.

They even have liquid salt and pepper for spaces.

and yes the moon does have a gravity and so does any object having mass ,which interestingly, includes us. yet gravity is directly proportional to mass and thus our gravity is negligible compared to the other massive things around us.

since the mass of moon is very much lesser than earth, its gravitational force is 1/6th of that of earth.

hope this helped,

sorry for the length of the explanation,

thank you,
