– On the surface, gravity is slightly higher at the poles than at the equator due to Earth’s shape (oblate spheroid) and centrifugal force from rotation.
– The Moon has about 1/6th the gravity of Earth’s surface, but gravity is not zero.
– Saturn has a different and much stronger gravitational field compared to Earth.
– 1 km beneath the Earth’s surface, gravity has slightly decreased but is still significant.
