The amount of gravitational force that acts on a space vehicle that orbits Earth is nearly as much as the vehicle's weight on Earth's surface but not quite the same. This is because the vehicle is still within Earth's gravitational field, which exerts a force on the vehicle, causing it to stay in orbit. The farther away from Earth the vehicle goes, the weaker the gravitational force becomes, but it will never be zero.
