WebJul 21, 2003 · Gravity and the Earth's Shape Gravity is the force that is responsible for the weight of an object and is determined by how the material that makes up the Earth is distributed throughout the Earth. Because gravity changes over the surface of the Earth, the weight of an object changes along with it. ... 1,000 meters (approximately 3,280 feet ... The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given by the norm . In SI units this acceleration is expressed in metres per second squared (in symbols, m/s or m·s ) o… WebDid the spacecraft escape the Earth's gravity? (No. Not even the International Space Station, at 250 miles up, escapes gravity. Weightlessness is caused by free fall, not escaping the Earth's gravity.) ...
