If I dropped the Earth onto the Moon, how fast would it fall? Would it fall as fast as a pebble would fall on?

the moon or as fast as a pebble would fall on Earth, since in effect you would also be dropping the Moon onto the Earth.If I dropped the Earth onto the Moon, how fast would it fall? Would it fall as fast as a pebble would fall on?
As the first person pointed out, it would be the moon that did most of the falling, but it wouldn't be *all* of it. The earth would only move about 1/80 of the distance between them.





If you dropped a pebble from the distance of the moon, with no air to resist it, it would reach the earth at a speed much greater than any pebble could fall in the atmosphere. It would probably be fast enough to burn up in the atmosphere. The moon would fall just a little bit faster than that because the earth would be moving toward it a little.





I don't know the formula for figuring out how fast the moon would be traveling if it stopped in its orbit and fell to the earth. I would think it would be many miles per second.If I dropped the Earth onto the Moon, how fast would it fall? Would it fall as fast as a pebble would fall on?
It wouldn't because the gravity of the earth out classes that of the moon so only the moon could fall onto the earth, and it would fall as fast as anything that is falling 362 ft per second I think, or something like that, but what would probably be more significant is that the resultant impact would be enough to crack more than a quarter of our planet off. Many scientists believe the moon broke off of the earth during the solar systems primordial stages by asteroid impact.
Another person who thinks the laws of physics can be violated at will. The moon has 1/6 the acceleration of gravity that Earth has, so the mass of the Earth would fall 1/6 as fast as the mass of the Earth dropped on the Earth would have.





The center of mass of the Earth - moon system is 1000 miles beneath the surface of the Earth. How could the Earth fall toward a point that already within its own mass?
As you may have noticed, the earth IS falling on the moon. Just like the moon is falling on the earth. Orbiting around eachother is just another way of saying they are actually falling.





A short story to explain: Suppose you can jump really high. You jump 2 metres high. What happens? You fall back to earth. Now jump 10km high. You probably will fall back to earth again. But suppose you jumped with a velocity of +-11km/s. Now you would escape from earth's gravity. You would orbit the earth, but what actually happens is that you keep falling onto the earth, but each time you miss it.
as the sizes are comparable....





if the orbital motion is stopped, both will fall towards the common center of mass, the final speed of one w.r.t. other will be less then that of a pebble at the time of contact because...





the centers of both will be at distance R+r (Sum of radii) at contact.





whereas a pebble comes closer to center of earth or moon.





and after that we will celebrate a BIG BANG HAHAHA
Both would attract each other but since the Earth has the larger mass the moon would more appear to fall to the Earth. Both centers of gravity would move towards each other with the moons center undergoing the most rapid movement.
As people already said the moon only would fall onm the earth provided there are no external forces except gravity on earth and moon.It would accelerate at 9.8 m / s ^2
its called gravity , and atmosphere,
