Answer #1

International space station is like an artificial satellite and it is located in low earth orbit.It revolves around the earth and gravitational force provides necessary centripetal force for its motion.

So it is false to say that International Space Station is located beyond the gravitational field of earth.Because any object can not orbit the earth without presence of gravitational field.

Gravitational force is the only external force acts on ISS.The cause of weightlessness in ISS is that it is always in free fall condition and we kniw that when a body remains in free fall condition then its apparent weight becomes zero.Since it also has a tangential velocity in its path so it always remains at proper distance from earth and never collide with earth.

    #1. ["Massing' Astronauts) Inside the International Space Station orbiting Earth, ordinary scales don't work for measuring weight since the space station is in free fall. However, the masses of astronauts can be determined using an oscillatory device known as an inertia balance that relies on springs rather than gravity for its restoring force. A 22.5 kg chair attached to a spring takes 1.30 s to complete one cycle of oscillation. With an astronaut sitting in the oscillating chair with feet...

  • What happens if you blow bubbles into a glass of lemonade on the international space station?...

    What happens if you blow bubbles into a glass of lemonade on the international space station? Since you are weightless in orbit, there's no up, down, left nor right. We define down on the Earth surface as the direction things tend to fall, down. On Earth bubbles rise if blown into a glass of lemonade (with a straw and a cover).

    You sometimes hear about "zero gravity" in places like the International Space Station. Since we know Newton's Law of Gravity, we know that gravity doesn't just "stop" anywhere. What is the ratio of the gravitational force from the earth on something in the International Space Station (orbiting an average of 385 km above Earths surface) to the gravitational force from the earth on that same object when it is on the ground?

    Astronauts in the International Space Station must work out every day to counteract the effects of weightlessness. Researchers have investigated if riding a stationary bicycle while experiencing artificial gravity from a rotating platform gives any additional cardiovascular benefit. What frequency of rotation, in rpm, is required to give an acceleration of 1.4g to an astronaut's feet, if her feet are 1.1m from the platform's rotational axis?

    The space station orbits Earth about 400 km above the surface of Earth (NASA.gov). At this height the force of gravity from Earth is only about 10% less than on the surface of Earth. Using the concepts of circular motion and gravitational forces explain the following: 1. Why does the space station not fall down? 2. Why do the astronauts float inside the space station?
