Which image below best represents the forces acting on the Earth due to the Sun's gravitational field?
A rock is initially on top of a mountain. A mountain climber carries the rock down the mountain and places it on the ground.
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.
Two identical spacecraft start out at rest 150,000 m apart. They then fire their rockets to move so that the distance between them doubles and they are again at rest. Both spacecraft must fire their rockets to stay at rest.
How did the spacecrafts’ change in position affect the gravitational potential energy of the system?
The gravitational potential energy did not change, because the spacecraft started at rest and ended at rest.
The gravitational potential energy decreased, because the spacecraft move farther apart.
The gravitational potential energy increased, because the spacecraft moved farther apart.
The gravitational potential energy does not change, because of the spacecraft move the same distance but in opposite directions.
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.
How does Newton's Third Law of Motion relate to gravitational forces?
An object at rest doesn't get pulled by gravity as much as one in motion.
An object will accelerate when acted on by the force of gravity.
Every mass pulls on every other mass in the universe with an equal magnitude but opposite direction.
