How does the force of gravity's magnitude change if you move one planet 4 times farther away from another?
The new force is the same as the original force.
The new force is 1/16 times the original force.
The new force is 1/4 times the original force.
The new force is 2 times the original force.
The new force is 4 times the original force
The new force is 8 times the original force
The new force is 16 times the original force
Two asteroids have moved 3 times farther apart from each other. how does the magnitude of the gravitational force between compare to when they were cloaser together?
The new force is 1/27 times the original force.
The new force is 1/9 times the original force.
The new force is 1/3 times the original force.
The new force is 3 times the original force.
The new force is 9 time the original force.
A mystery planet that is EXACTLY like the Earth has been discovered on te other side of the Sun. We could never see it because it is always exactly opposite the Earth. Only this duplicate Earth is moving away from the Sun when it was seen. It is currently twice as far from the Sun as the Earth. How does the gravitational force between this duplicate Earth and the Sun compare to the gravitational force between our Earth the Sun?
The force is 4 times as big as the force between our Earth and the Sun.
The force is 2 times as big as the force between our Earth and the Sun.
The force is 1/2 times as big as the force between our Earth and the Sun.
The force is 1/4 times as big as the force between our Earth and the Sun.
The force is 1/16 times as big as the force between our Earth and the Sun.
Two asteroids move to a position that is 9 times closer than their original position. How does the magnitude of their new gravitational force compare to the old gravitational force?
The new force is 1/81 times the old force of attraction.
The new force is 1/9 times the old force of attraction.
The new force is 9 times the old force of attraction.
The new force is 81 times the old force of attraction.
In a distant solar system, two planets move towards each other. They are now half the distance they were to start with. How does the magnitude of the new force of attraction compare to the origial force of attraction between them?
The new force of attraction is 4 times the original force of attraction.
The new force of attraction is 2 times the original force of attraction.
The new force of attraction is 1/2 times the original force of attraction.
The new force of attraction is 1/4 times the original force of attraction.
Two people walk from 100 meters apart to 25 meters apart. how does the magnitude of the gravittional force between them change?
The new force of attraction is 4 times the original force of attraction.
The new force of attraction is 8 times the original force of attraction.
The new force of attraction is 16 times the original force of attraction.
The new force of attraction is 1/4 times the original force of attraction.
The new force of attraction is 1/16 times the original force of attraction.
Two meateors are traveling 2 million miles apart. Later they are 6 million miles apart. How does the magnitude of the new force at 6 million compare the previous force.
The new force if 1/6 times the original force.
The new force if 1/36 times the original force.
The new force if 1/9 times the original force.
The new force if 3 times the original force.
The new force if 9 times the original force.
Two invading spaceships feel a gravitational force between them of "X." Later in their flight, they move to a position where they feel a 1/4 of their original force. By what factor did their distance of seperation change compared to their original distance? (This problem is backwards from the previous problems.)
Their new distance is 1/16 times their old distance.
Their new distance is 1/4 times their old distance.
Their new distance is 2 times their old distance.
Their new distance is 16 times their old distance.
Two students feel a force of 2x10^{-9} Newtons when they are standing in the senior circle on the breezeway. Later the gravitational force between changes by a factor of 16 time their original force. By what factor does the distance between them change?
