No, one is not weightless in water. When submerged in water, the body still experiences the force of gravity, which gives it weight. However, the buoyant force of the water counteracts some of the gravitational force, making the body feel lighter in water than it does in air. This is why people can float in water, as the buoyant force is able to support some of their weight. **

Yes, in space, an astronaut would be weightless everywhere. This is because weight is a measure of the force of gravity acting on an object, and in the microgravity environment of space, there is very little gravity pulling on the astronaut. As a result, they would experience a sensation of weightlessness regardless of their position within the spacecraft or in open space. **

No, one is not weightless in the stratosphere. While the gravitational force is slightly weaker in the stratosphere compared to the Earth's surface, it is not significant enough to make a person weightless. Weightlessness is typically experienced in outer space or during free-fall, where the effects of gravity are significantly reduced. In the stratosphere, the force of gravity is still strong enough to keep a person grounded. **

You are weightless on the trampoline at the very top of your jump when you reach the peak of your trajectory. At this point, gravity has momentarily stopped pulling you down, creating a sensation of weightlessness. This feeling is similar to the sensation experienced by astronauts in space when they are in a state of free fall. **

Completely weightless miserable fearful means feeling a complete lack of physical or emotional support, experiencing extreme unhappiness and discomfort, and being overwhelmed by intense fear and anxiety. It describes a state of being where one feels utterly alone, hopeless, and terrified. This phrase conveys a sense of total despair and helplessness. **

A body is weightless when it is in a state of free fall, such as when it is in orbit around the Earth or when it is falling from a great height. This occurs because the force of gravity acting on the body is balanced by the body's inertia, resulting in a sensation of weightlessness. Therefore, a body can be weightless at any height as long as it is in a state of free fall. **

During a parabolic flight, the plane follows a specific trajectory that allows for brief periods of weightlessness. This occurs when the plane is in free fall, causing everything inside the plane to fall at the same rate as the plane itself. As a result, there is no sensation of weight because gravity is effectively canceled out by the acceleration of the plane. This creates a microgravity environment similar to what astronauts experience in space. **

No, one is not weightless at the center of the Earth. At the center of the Earth, the gravitational forces from all directions cancel each other out, resulting in a net force of zero. However, weightlessness is the absence of gravitational force, which is not the case at the center of the Earth. Therefore, one would not be weightless at the center of the Earth. **
