How Come The Moon Is So Strong
hi peeps,
thought of this last night while in bed and could not think of an answer so could not get back to sleep, please help me me sleep tonite, right.......while on the moon the astronaughts could jump quite high because the gravity is only aprox 1 sixth of the earths gravity, soooooooo, if the moons gravity is only 1 sixth of the earth's how can it affect the oceans and cause tides ??, please any answers in laymans terms if poss, thanks in advance for any replies

The moon and earth are tidally locked and together they cause the tides. The water facing the moon bulges towards the moon but also the water on the other side of the earth bulges away from the moon.

easiest
just as it affects the astronauts, so it affects the tides.
It is just a question of arithmetic
Newton the inventor of all this had a similar difficulty. He realised that gravity was the cause 1665 in the plague year - but it took him another 20 y to write it down ( helped by Halley I think) 1687
beause he was using the wrong figure for the mass of the moon - (so the calculations didnt balance)

ends with a coy - why measure it observationally when you can calculate it, so long as you know the mass of the earth
