Due to moon's attraction ocean tide rises................?

Question

but earth has its own gravity....
it cannot cancel the force???

Answer 1

Yes, the moon which orbits earth does affect the earths surface, most notably the oceans and seas. Try to picture it this way, you have a stick which represents the earth and attached to the top of that stick is a piece of string with a ball attached to the end. If you were to take the stick in hand and rotate it the ball would begin to circle the stick. The string represents the earths gravitational pull on the moon. You will notice that although the ball circles the stick, the ball itself as it travels around the stick actually pulls on the stick itself and begins to make it wobble. This is the same principle for the earth and moon concerning their relation to one another concerning gravity. This is why they do not cancel it other out.

Answer 2

Object A cannot cancel out the gravity of Object B, however the effect of Object A's gravity can almost mask the influence of Object B's gravity. The same is true with the earth and the moon, the moon will always pull on the oceans but the massive gravity of the earth (which is also what is keeping the moon in orbit) is keeping the oceans here. But since the moons gravity cannot be totally masked by the earth the oceans do rise a very small fraction of the distance of the earth to the moon. I hope this helped.

Answer 3

Earth's gravitational(G) pull is much greater than that of moon(less than 1%of Earth's G pull during high tides!!) on the waters.

some simple maths:
let Earth's G pull= 100 units
let Moon's G pull= 1 unit (full moon day)
let Moon's G pull= 0 unit (no moon day/dark night)
let ocean level= 0 (no moon day/dark night)
now, on full moon day, the net effective G pull of Earth is 100 - 1 = 99 units. Hence water level rises by about 1%

Answer 4

yes. because as per the cycle moon happen to be the nearest on its orbit. every fortnightly. and it is considered that the attraction of moon becomes more during this time. in that case all the object perticularly water tend to have gravitational force from both the side. but as the earth having more dominating Gravi Force the tide took place.this is what my logic about it.

Answer 5

notice that the ocean doesn't rise up all the way to the moon...
it only shifts a little bit in comparison to the total size of the ocean
i wondered once if the air bubble in a carpenter's level would read different if the moon was in the east in the morning, and in the west in the evening,
but do the math,
and it's like a speck of dust is going to affect a basketball... not!

Answer 6

good point.. but true the earth's grav on sea/ocean water is not as strong... other reasons this is so is due to the other forces acting on the currents/waters, as is the natural unstableness of water(free flowing)

Answer 7

i think that peace with good peoples can do something
and they can faraway the force
