One of the more unusual consequences of the powerful earthquake was the effect it had on Earth's gravity. A minor alteration in local gravity was first reported soon after the disaster, but newly ...

The second major reason for the difference in gravity at different latitudes is that the Earth's equatorial bulge (itself also caused by centrifugal force from rotation) causes objects at the Equator to be farther from the planet's centre than objects at the poles. Because the force due to gravitational attraction between two bodies (the Earth ...

An astronaut goes out for a "space-walk" at a distance above the Earth equal to the radius of the Earth. What is her acceleration due to gravity? At first I thought it would just be zero, because the astronaut was weightless. But then I realized she might be moving like a satellite, which is in free-fall (I think), rather than weightlessness.

Actually, the force of gravity would increase. Gravity depends not only on the mass of the objects but also the distance between them. As the Earth shrinks, the distance between the object and the center of the earth decreases, therefore the force of gravity will increase.
