Gravity pulls the water down more than it pulls the boat down.

BUOYANCY in liquid?
Buoyancy regards flotation based on its displacement over a liquid. By the principal and phenomena of buoyancy the flotation of ships and bodies over water is possible.
What is a force that pulls material down a slope?
Gravity Also, Erosion and Weathering help out the process as well.
What does force of gravity mean?
Force of Gravity is the force with which the earth attracts bodies towards its center. It makes it possible for the bodies (mass) to stay firm on the surface of the earth. When we throw something upwards, it comes down as a result of the force of gravity.
Does gravity go up or down?
Gravity is a force between 2 bodies. Gravity goes in the direction towards the body of greater mass. For things on earth, gravity is in the "downward" direction (i.e. towards the earth), since the earth is of greater mass than other objects.
Why does acceleration due to gravity always point vertical downward?
Acceleration due to gravity is due to the force of gravitation exerted on a body by the earth. All bodies get attracted towards the centre of the earth. So the acceleration is always pointed vertically downwards.
Could the effects of zero gravity on human bodies be reduced during a long space voyage?
Our bodies require gravity for, among other things, proper kidney/bladder function. However, the effects of zero gravity can be reduced by "artificial" gravity through the use of essentially a big centrifuge. This would simulate the downward pull of gravity. I remember reading a study somewhere a long time ago that talked about this. This is why on the science fiction shows you often see a part of a space ship rotating; this area not only gives an artificial gravity effect, but space-goers would spend a certain amount of time in there to simulate gravity for their bodies.
How does the strength of gravity affect acceleration of falling bodies?
All bodies with mass are affected by gravity. Gravity pulls at a rate of 9.8m/s/s
Can there be gravity between mars and earth?
All celestial bodies exhibit some kind of gravitational pull on all other bodies. Hence, yes, it is very much possible to figure out the pull between the Earth and Mars. So yes, there can be, and is, gravity between our planets. Needless to say, the effect of Mars gravity on earth is overwhelmed by the effect of the suns gravity on earth. But it still exists.
Which of the two forces are important in floating bodies?
water pressure which is effected by gravitational force and buoyancy
Why dont the large bodies attract smaller bodies?
They do. It is called gravity
Is gravity stronger when objects are far apart?
The use of word gravity here is totally wrong as gravity represents the force of gravity which we denote by symbol g, having an approx. value of 9.8 m/s2. When two bodies move apart their Gravitational Force reduces..... The Gravitational force is inversely proportional to the square of the distance b/w their centers. The force of gravity acting on those two bodies remain same on the earth. and it always acts in the downward direction......... Please note that force of gravity and Gravitational Force are two different things...
Why two bodies attract?
gravity
