Water exerts a force on anything that comes into contact with it, this is known as Hydric force. The force always pulls at the object, drawing it down. You will notice that if you put your hand under water, and bring it out slowly, the water seems to cling to your hand as it breaks the surface. This is why. Stones can't pull themselves out of water, so the Hydric force overpowers them and pulls them down.
If the object is floating on the surface of the fluid, like a boat, then the fluid is exerting the normal force on the object. The normal force is a force that is equal and opposite to the force of gravity acting on an object. If the object is under the water then the weight of the water above the object is pushing down on it.
Gravity.

No force is required to keep something moving. According to Newton's Second Law, you need a force to speed something up, or to slow something down - not to keep it moving.
Gravity. It's the same force which pulls things down even without water.
Water down under is ground water.

Repression
because the upthrust force of the water acting on the stone was pushing the stone upwards meaning it was acting against the downwards weight of the stone (its weight). This meant that the downwards force was decreased and therefore felt lighter :)
Friction is a force that opposes all movement to slow down a moving object.

Ground water. ;)
the term for under water is ''ground water ''.
