Anything in an orbit is constantly accelerated.
If that sounds peculiar to you, it's because you think 'accelerate' means 'speed up'.
It doesn't. It means 'change speed or direction or both'.
If an object is not moving at a constant speed in a straight line, then it's accelerating.
An object in an orbit is constantly changing direction. So it's constantly being
accelerated, even if its speed never changes.
Yes that is what they are experiencing.
he was revering to a high speed light that passed by them while in orbit around earth . I believe they were going twice the speed of sound at the time. there's been several astronauts reports of UFOs' while orbiting earth not just US. astronauts. Russian astronauts for instance.
False.Orbiting astronauts feel weightlessness since the gravitational pull of the Earth is balanced by the centrifugal force due to the circular orbital motion, which balance each other out since the spaceship is in orbit. That is, the weightlessness is because of no net force on the astronaut.In a nutshell, if you are orbiting, then irrespective of what height you're doing it, you'd be weightless.
Any astronaut would experience weightlessness while orbiting the Earth.Any astronaut would experience weightlessness while orbiting the Earth.Any astronaut would experience weightlessness while orbiting the Earth.Any astronaut would experience weightlessness while orbiting the Earth.
Chinese astronauts are known as Taikonauts.
Yes that is what they are experiencing.
Free fall
Noop. In fact, as the Shuttle is accelerating, the astronauts are experiencing not only the pull of gravity, but also the acceleration of the rocket. For the comfort of the crew, they try to keep the excess gravity to about 4 G, basically 4 times the pull of gravity. Only after the engines have stopped, and the shuttle is no longer accelerating, will the astronauts feel weightless, as the Shuttle and astronauts are all falling around the Earth at the same speed.
The docking of the Gemini spacecraft.
In Newtonian physics they are not following a straight path, therefore they must be accelerating.However in General Relativity they are following a locally straight path through curved spacetime, therefore they are not accelerating.
Astronauts float in an orbiting spaceship because both the spacecraft and the astronauts are in a state of free fall towards Earth. While the ship is constantly falling due to gravity, it also has a forward velocity that keeps it in orbit, creating a sensation of weightlessness. This condition is often referred to as microgravity, where the effects of gravity are still present but not felt in the same way as on the Earth's surface. As a result, astronauts appear to float relative to the spacecraft.
Astronauts appear weightless in their Earth-orbiting spacecraft because both the spacecraft and the astronauts are in a state of free fall towards Earth. While the spacecraft is moving forward at a high velocity, it is also falling towards the planet due to gravity. This continuous free fall creates a condition known as microgravity, where the effects of gravity are still present but are not felt by the astronauts, making them seem weightless relative to their surroundings.
Yes, the International Space Station (ISS) typically has a crew of astronauts on board conducting scientific research, maintaining the station, and performing other tasks. The crew size varies but usually ranges from 3 to 6 astronauts.
Orbiting affects astronauts in several ways, primarily due to microgravity conditions. This environment can lead to muscle atrophy and bone density loss, as the body adapts to the lack of gravitational force. Additionally, astronauts may experience fluid redistribution, which can cause facial swelling and changes in vision. Psychological effects, such as isolation and confinement, can also impact their well-being during extended missions.
Astronauts feel weightlessness inside an orbiting spacecraft because both the spacecraft and the astronauts are in a continuous state of free fall towards Earth. As the spacecraft travels at high speeds in orbit, it falls towards the planet but also moves forward, creating a curved path that matches the curvature of the Earth. This balance between gravitational pull and forward motion results in a sensation of weightlessness, as there is no support force acting on the astronauts. Essentially, they are in a state of microgravity, experiencing the effects of gravity but not feeling it as they would on the surface.
That comes roughlyclose, if you happen to be the moon. Astronauts orbiting the earth make several orbits per day.
The space station currently orbiting Earth is called the International Space Station (ISS). It serves as a research facility for various countries and is inhabited by astronauts from around the world.
