How do astronauts in orbit experience weightlessness?
Astronauts in orbit experience weightlessness because they are in a state of continuous free fall towards the Earth. This creates the sensation of floating in space, as there is no force pushing against them to create the feeling of weight.
What there is no gravity at the .?
center of earth
What happens to a spacecraft when its forward motion combines with its freefall?
When a spacecraft is in freefall and also moving forward, it remains in orbit around a larger body like a planet or moon. This combination of forward motion and freefall creates a balance where the spacecraft continuously falls towards the larger body while also moving forward at a speed that prevents it from crashing into the body.
A friend says that astronauts in orbit are weightless because they're beyond the pull of earth's gravity correct your friend's ignorance?
Weightlessness in orbit is not due to being beyond Earth's gravity, but rather to being in a state of continuous free fall around the planet. In orbit, the spacecraft and everything inside are falling towards Earth at the same rate, creating the sensation of weightlessness. Gravity is still present in orbit but it is balanced by the spacecraft's forward motion, creating an apparent state of weightlessness.
Is it possible for an object in freefall to have no acceleration?
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
Because of free fall astronauts appear this way in orbit?
Because of free fall, astronauts in orbit appear weightless and float within their spacecraft. This is due to the spacecraft and everything inside it, including the astronauts, all falling towards Earth together at the same rate. The sensation of weightlessness is a result of this continuous state of free fall.
Are astronaunts in orbit around earth really weightless?
The astronauts appear to be weightless as they are in a constant freefall, falling at the same speed as the space vehicle they are on. They are 'falling' but due to their angular speed, they are 'falling' around the earth, so don't crash into it. They still have their mass, but you can't really weigh the astronauts as any scales you try to use will read zero as the scales will also be 'falling' at the same rate.
When astronauts float while in orbit because inertia and what are balanced in orbit?
Gravity
What is the condition for zero gravity?
freefall or stable orbit
What is formed by combining forward motion and freefall?
Orbit
Why do astronauts float weightlessly in space?
There is (apparent) zero gravity. The absolute gravity in orbit is about 90% of what it is on the surface of the earth, but the effective gravity is zero, and for a good reason.The fact is that in orbit, you are actually falling, but your forward speed is such that the curvature of the planet is dropping at the same rate that you are falling.And the astronauts are falling at the exact same speed as their capsule. This is called freefall.
What happens during a space walk does the International Space Station stop or it continues at the same speed?
The space station continues at the same speed. The spacewalker will also travel at the same speed. Their relative speed however will be near zero however because they are travelling together. In effect their is no real way for a spacecraft to speed up or slow down without changing its orbit.
Are astronauts weightless in orbit?
As there is no gravity in space, everything will float........... Because They're in free fall ........
Because of free fall astonauts appear this way in orbit?
Because of free fall in orbit, astronauts experience a continuous state of falling towards Earth while moving forward at a high speed. This results in a sensation of weightlessness, giving the appearance that they are floating or flying inside the spacecraft.
How do astronauts in orbit experience weightlessness?
Astronauts in orbit experience weightlessness because they are in a state of continuous free fall towards the Earth. This creates the sensation of floating in space, as there is no force pushing against them to create the feeling of weight.
Are astronauts really weightless in orbit?
No.
What are 4 examples of earth's gravitational pull?
Keeping the Moon in orbit around Earth. Holding objects on the surface of the Earth. Influencing the tides in the oceans. Allowing astronauts to experience weightlessness in space stations or during freefall.
