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 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?

    The earth has a net negative charge of about -4.3 x 105 C. Since this charge is distributed more or less uniformly over the spherical earth, the force due to this charge is the same as if it were all placed at the Earth's center. A 6.0 kg satellite is orbiting with an orbital radius of 55000 km. If the satellite were also charged, then there would be an electric force in addition to the gravitational force a. What charge...

    Which of the following statements are true? Because the Earth has mass it produces gravity. There is no gravity at the space station I need to do work to move a satellite from lower to higher orbit. Because the force of gravity is a conservative force and because it acts as a centripetal force it does no work, the mechanical energy of Earth is conserved and it will not crush into the Sun. Since Moon has no air, there is...
