Question

An astronaut inside a small space ship orbitting around the earth cannot detect gravity. If the space station orbitting around the earth has a large size, can he hope to detect gravity?

Answer 1

Hi

Here is your answer,

Inside a small spaceship orbitting around the earth the value of acceleration due to gravity g, can be considered as constant and hence astronaut feels weightless.

If the space station orbitting around the earth has a large size, such that variation in g matters in that case astronaut inside the spaceship will experience gravitational force and hence can detect gravity. EX:- On a moon due to larger size gravity can be detected.


Hope it helps you !

Answer 2

Hi friend,

We can detect the gravitational force in larger areas.

Reasons:-

Our earth has larger gravitational force so as even the smaller objects can experience it.While in other planets or in orbits for smaller objects can't observe the gravitational pull.

For ex:-

Moon has the gravitational power of about (1/6) times the earth.

This means earth has 6 times stronger gravity than the moon.So moon and other planets or orbits shows influence of gravity only on larger substances.

Hope you got some ideas.
