Earth’s rotational velocity is maximum at the equator (on earth, centripetal force is maximum at the equator).
· When a spacecraft is launched into orbit, it should end up spinning around the Earth quickly enough not to be pulled back in by the Earth's gravity.
· The huge rockets used in launching a spaceship help this to happen by giving a huge amount of thrust, enough to achieve escape velocity.
· However, the spin of the Earth itself can help give it a push as well.
· Anything on the surface of the Earth at the equator is already moving at 1670 kilometers per hour (rotational velocity of earth).
