The amount of gravitational force that acts on a space vehicle while in Earth orbit is A) the same as the vehicle's weight on Earth's surface. B) nearly as much as the vehicle's weight on Earth's surface. riearly zero. In comparison with other fundamental forces, the universal gravitational constant G indicates that gravity is A) strong. B) very strong. TS) very weak. If you drop a stone into a hole drilled all the way to the other side of Earth (neglect the molten core), the stone will A) speed up until it reaches Earth's other side. B) come to an abrupt stop at Earth's center. Q speed up until it gets to Earth's center. D) slow down until it reaches Earth's center.
