Question

A spaceship is in orbit around the earth at an altitude of 12000 miles. Which one of the following statements best explains why the astronauts experience weightlessness

Answer 1

Weightlessness

• The phenomenon of "weightlessness" occurs when there is no force of support on your body.
• When your body is effectively in "free fall", accelerating downward at the acceleration of gravity, then you are not being supported.
• Weightlessness is the entire or close total nonappearance of the sensation of weight.
• This is likewise named zero-g, despite the fact that the term is all the more effectively "zero g-constrain." It happens without any contact powers upon articles including the human body.
• The powers which bolster bodies very still in a moderately solid gravitational field, (for example, on the surface of the Earth), is ordinarily seen as weight. These weight-sensations start from contact with supporting floors, seats, beds, scales, and so forth.
• A vibe of weight is likewise created, notwithstanding when the gravitational field is zero, when contact powers follow up on and beat a body's latency by mechanical, non-gravitational powers, for example, in a rotator, a pivoting space station, or inside a quickening vehicle.
• At the point when the gravitational field is non-uniform, a body in free fall encounters tidal impacts and isn't calm. Almost a dark gap, such tidal impacts can be extremely solid.
• On account of the Earth, the impacts are minor, particularly on objects of moderately little measurement, (for example, the human body or a shuttle) and the general vibe of weightlessness in these cases is saved. This condition is known as microgravity and it wins in circling rocket.

Example

When you are in an auto on a slope or an amusement stop ride that made you feel weightless? I trust so or else this probably won't bode well.

As you go up a slope or a ride, you sink into your seat since you are being pushed up. This is the reason you 'sink'.

At that point at simply the correct minute (at the highest point of a slope for instance) the thing that is pushing you, lice a seat, is moving at a similar speed you are. This implies it is never again pushing you. When you are not being pushed you feel weightless.

At that point gravity kicks in and maneuvers you down again into your seat Now that your butt is in the seat you no longer feet weightless in light of the fact that you are pushing on the seat.

So in space, the space travelers are essentially falling at a similar speed of their ship.

This happens in light of the fact that the power of gravity is so little at the high of state of mind, yet it is still there. So they can 'skim' for quite a while.

The closer they come to earth to greater gravity draws in them and the quicker they fall

Simply recollect that when you are not contacting anything you feel weightless, and when 2 things are moving at the speed, nothing is contacting.

The best Statement that Explains Weightlessness is the spaceship is in free fall and its floor cannot press upwards on the astronauts
