What is a sentence for weightlessness?
The weightless astronaut landed on Mars, which has no gravity.
What is an astronauts weight in space?
An astronaut's weight in space is effectively zero due to the condition known as microgravity. While their mass remains the same, the sensation of weightlessness occurs because both the astronaut and the spacecraft are in free fall towards Earth, creating the illusion of weightlessness. This means astronauts experience a state where they float rather than feel their weight, despite the presence of gravity still acting on them.
Is it true that an astronaut is weight in space Explain answer?
Yes, it is true that an astronaut's weight in space is effectively reduced due to the microgravity environment. While mass remains constant, weight is the force of gravity acting on that mass. In space, particularly in low Earth orbit, astronauts experience free fall, creating the sensation of weightlessness, even though gravity is still present at about 90% of its strength compared to Earth's surface.
If an astronaut is weightless orbiting the earth at 100 miles up would you experience weightlessness at the top of a 100 mile step ladder What equations would prove or disprove?
The person on the ladder would not feel weightless because they are not in orbit, they are simply at a high altitude. If they let go, they would fall straight down towards the earth's center just as any other object which is being pulled on by gravity.Orbit is achieved through velocity. With enough thrust, a rocket is able to propel an astronaut to a speed which will send him beyond the earth's gravitational field and straight into space (ie: "escape velocity"). However, by controlling the level of thrust and angle of inclination, the astronaut can be placed in an area of space that is somewhere "in-between" the pull of earth's gravity and the escape velocity. This is called "orbital velocity". The astronaut achieves ORBIT, and he is in a constant free-fall circling around the earth: not quite fast enough to escape the earth's gravity, but not so slow that he falls back to earth.When a spacecraft needs to return to earth, thrusters are fired in the direction of orbit, which decreases forward speed, and allows the craft to return to earth via the earth's gravitational field with help from atmospheric drag.
How does sunlight reach an astronaut on the international space station?
It arrives directly from the sun or comes in via the reflection off the earth, the moon, or anything else orbiting nearby.
Why does an astronaut float in an orbiting spaceship?
An astronaut floats in an orbiting spaceship because they are in a state of continuous free fall towards the Earth, which creates the sensation of weightlessness. This is due to the balance between the astronaut's forward motion and the gravitational pull of the Earth, allowing them to float inside the spaceship.

How does an astronaut's mass while orbiting in the space shuttle compare with his mass while standing on the earth's surface?
An astronaut's mass remains unchanged whether they are in orbit aboard the space shuttle or standing on Earth's surface; mass is a measure of the amount of matter in an object and does not vary with location. However, the astronaut experiences weightlessness in orbit due to the microgravity environment, which is a result of the shuttle and astronaut being in free fall together around the Earth. This sensation of weightlessness can lead to the common misconception that mass decreases in space, but it does not; only the effects of gravity on the astronaut's body change.
How do you experience weightlessness on earth?
You can approximate weightlessness in a swimming pool. NASA astronauts practice maneuvers under water.
Why an astronot in orbiting satellite has a feeling of weightlessness?
the net force on bodies in stable orbit is nil, the force of gravitational attraction , is balanced by the centripetal force of velocity in a circle. . example, any orbit radius ( if orbit time not important) choose your orbit radius, calculate force of gravity, tailor velocity to produce balancing centripital force . f=((G*m1*m2)/d^2) force of gravity f = m2 *( v^2/d ) centripetal force G = newtons constant m1 = earth mass m2 = satellite mass d = orbital distance

An astronaut inside a small space ship orbiting around the earth cannot detect gravity.If the space station orbiting around the earth has a large size can he hope to detect gravity?
If the size of the space station is large enough, then the astronaut will detect the change in Earth's gravity (g).
What is a situation in which an object is weightless?
An object is weightless when it is in free fall, such as when an astronaut is orbiting the Earth in the International Space Station. In this situation, the object is technically still affected by gravity but experiences a sensation of weightlessness because it is falling at the same rate as its surroundings.
What is true weightlessness?
True weightlessness refers to the sensation experienced by objects or individuals when they are freely falling in a vacuum environment, without any external forces acting on them. This occurs when the force of gravity is canceled out by the acceleration of the object. Astronauts in space experience this sensation due to their spacecraft orbiting the Earth.
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.
Is an orbiting astronaut subject to zero gravitational force?
An orbiting astronaut experiences a gravitational force that keeps them moving in a curved path around a celestial body, such as a planet or moon. This force is what causes the astronaut to stay in orbit. It is not that there is zero gravitational force, but rather that the force is balanced with the astronaut's velocity so they remain in a stable orbit.
How do you achieve weightlessness?
Weightlessness is achieved when an object is in free fall, meaning it is falling under the influence of gravity alone without any forces acting against it. This condition is commonly experienced in orbiting spacecraft, where both the spacecraft and its occupants are in a continuous state of free fall towards Earth but have enough horizontal velocity to keep missing it. This creates the sensation of weightlessness. Weightlessness can also be simulated on Earth using parabolic flight or drop towers.
