#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...

"apparent weightlessness” Which of the following statements explains why astronauts seem weightless while in an orbiting spacecraft? a) There is no gravity in space b) They are in a state of free fall, accelerating toward the earth at the same rate as the spacecraft c) They are far enough from the earth that gravity is not able to reach them d) None of the above

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?

The International Space Station whose mass is 420 tons is orbiting at an altitude of about 400 km above the earth's surface. The mass of the earth is 5.976 × 102 4 kg and the radius of the earth is 6.378 × 106 m. (a) What is the gravitational force exerted on the Space Station by the earth? (b) Assuming a circular orbit, what is the period of the International Space Station's orbit? (c) Assuming a circular orbit, what is...

Does the force of gravity
alone provide the means for the centripetal force, is this why they
are equal ? For explaining why there is no normal force, could you
see it as the astronaut having the same acceleration as the ship
and so the relative acceleration = 0, so it's under the illusion
almost of having no acceleration so there's no force ? Please !! If
you have different reasoning please share. I'm just trying to wrap

Two astronauts, each having a mass of 70.0 kg, are connected by a 9.0 m rope of negligible mass. They are isolated in space, orbiting their center of mass at speeds of 5.50 m/s. (a) Treating the astronauts as particles, calculate the magnitude of the angular momentum. (kg·m2/s) (b) Calculate the rotational energy of the system. (c) By pulling on the rope, one of the astronauts shortens the distance between them to 5.00 m. What is the new angular momentum...
