What is a sentence for weightlessness?
The weightless astronaut landed on Mars, which has no gravity.
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.
What is so special about being an astronaut?
Being one of the few people who get to go into space, to experience living in a weightlessness environment, to look down on the earth from above, and to fully appreciate the vast emptiness of space. I guess what one person sees as being special will vary with the next, however there are many people that have an appreciation and a curiosity to wonder what it would be like.
What is a sentence for weightlessness?
The weightless astronaut landed on Mars, which has no gravity.
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 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.
Why isn't an astronaut in our solar system in zero gravity?
An astronaut can never be in zero gravity in our solar system, because there is gravity (usually) from the Earth, and always from the Sun. It is important to distinguish weightlessness from zero gravity. Weightlessness occurs in a gravity environment in which the person is freefalling, hopefully in orbit. In a freefall condition, there is no friction to retard your fall, so you feel nothing pressing against you, and thus you feel weightless..When in orbit around the Earth, an astronaut is in freefall, and is therefore weightless, but there is still gravity. When travelling between the Earth to the Moon, the astronaut is still in orbit around the Sun, and is therefore freefalling weightlessly.
How far from earth do you have to be to experience weightlessness?
You have to be outside of the gravitational pull in the atmoshpere. Answer: Weightlessness can be achieved:* in Earth's atmosphere in an aeroplane doing a dive or on carnival rides (Drop of Death)* when in orbit around the Earth or other body.* there are several points (Lagrange points)in the Earth/moon system where the gravitational attraction of the two bodies cancels out producing weightlessness.
Do you weigh less on Earth than in a spaceship orbiting 800 km above Earth?
No, you actually weigh slightly less in a spaceship orbiting 800 km above Earth compared to your weight on the surface of Earth. This is because weight is the force of gravity acting on an object, and gravitational force decreases with distance from the Earth's center. In orbit, you experience microgravity, which gives the sensation of weightlessness, but your mass remains the same. Thus, while you still have weight in a spaceship, it is less than what it would be on Earth's surface.
