If you stand on the moon. There is very little gravity. Jump higher etc.
So how come the moons gravity pulls our tides in and out twice a day?
And as the earth has bigger mass and more gravity? Why dosent the earth attract the moon intowards us?

This is an ungoogled guess from a layman with a small brain

It's the physical presence of the moon that causes the tides not the moon's gravity.

I read somewhere that the earth IS attracting the moon towards us - extremely slowly.

A very good question. The earth does pull on the moon's surface althought obviously it causes no water tides but does crack rocks etc on the moon's surface. Theoon is moving away from us at about 2cm a year I believe but stand to be corrected on the distance.

The nature of gravity creates a warp in space which locks it into its orbit round earth. I wish I could explain the mechanics of this simply and think it would be best leaving it to some astro physicist millersmadder on here.

If you don't know the answer crash you shouldn't be on their thread. 😉

[rolymiller]

Basically the fabric of space is warped by gravity and you could argue that we should by the same argument be moving closer to the sun when on fact similarly we are moving away very slowly

Another one for the clever folk of this forum.
If a bus is driving along a road at 40mph and a fly entered the bus through a open window and is traveling at 20mph. Once the fly goes inside the bus how fast is it actually traveling?

So . No brainy people on here then.?

Get your own thread.

Gravity is a force that depends on the mass of objects and the distance between them, but it is always a force of attraction. The earth pulls on the moon and the moon on the earth, but because it is an attractive force the moon doesn’t fly off into space.

Either that or it’s a big invisible string.
