Gravitational Field G

Rate this statement: No force due to Earth's gravity acts on astronauts inside the orbiting space station.

• always true while in orbit, the astronaut is weightless

• sometimes true while in orbit, depending on the angular speed of the space station

• always false, centripetal force is needed

• Increase because gravitational force increases

• decrease because gravitational force decreases

• decrease because gravitational force increases

• nothing, weight is not affected by gravitational force

How did the rock’s change in position affect the gravitational potential energy of the rock-Earth system?

• The gravitational potential energy did not change, because the rock started at rest and ended at rest.

• The gravitational potential energy does not change, because the rock is still on the surface of Earth.

• The gravitational potential energy decreased, because the rock moved closer to the Center of the Earth.

• The gravitational potential energy increased, because the rock is closer to the Center of the Earth.

How does the gravitational force exerted by the Earth on you compare with the gravitational force exerted by you on the Earth?

• The Earth pulls on me more than I pull on the Earth.

• I pull on the Earth more than the Earth pulls on me.

• The Earth pulls me the same amount as I pull on the Earth.
