What would Earth be like if the moon was closer?

With the Moon coming closer and closer, the Earth rotation would speed up, our days would become shorter and shorter, global temperatures would go down and no one would worry about climate change anymore. Unless asteroids burned the Earth to ashes, then there would be no one to worry about anything.

What would happen if the moon was farther away from Earth?

There is a physical principle called the conservation of momentum, which says that the Earth will have to slow down as the moon gets farther away. This means that the length of the day increases slightly – more hours in a day is probably all you wanted!

What would happen to the gravitational attraction of the moon were 480 000 mi away?

What would happen to the gravitational force if the moon were moved to a distance of 480,000 miles? The gravitational force would be the same because gravity depends on the mass of the Earth and the moon, not the distance between them.

What if the moon was half as far away?

The Earth has about 80 times the mass of the Moon, so if you could situate yourself exactly halfway between them, the Earth would pull on you 80 times harder than the Moon. But it’s worse than that; gravity drops as the square of the distance, and the Moon is pretty far away.

How would the gravitational force between Earth and the Moon differ if the Moon were twice as far as it is now?

How would the gravitational force between the earth and the moon differ if the moon were twice as far as it is now? It would decrease by less than two times. You just studied 7 terms!

How would the gravitational force between the Earth and moon differ if the Moon is twice as far as it is now?

(a) Yes, if the Moon were twice as massive, the gravitational force of the Earth on the Moon would be twice as much, since the gravitational force is proportional to both masses involved. This means that the rocket would have to exert a larger force to balance its weight leaving the Earth than leaving the Moon.
