To push himself forward (by Newton's Third Law).
At the bottom of the pool.
A fish uses its fins to push water backwards and propel itself forwards.
Their bodies are streamline to help them swim through water quickly against water resistance (a force) . What pushes them backwards is water resistance
Newton's Law - For every action there is an equal and opposite reaction. In order for you to move forward, there must be a force going backward. That is evidenced by the backward motion of the log.
a rube, or simply a naive person. do they drink evian water? - that's naive spelled backwards
Boat motors work by converting fuel into mechanical energy, which is used to turn a propeller. The propeller then pushes water backwards, creating a force that propels the boat forward.
An oar pushes the water and the water pushes the oar.
Gravity pulls "down" on stuff. Gravity imparts weight to a mass because it is pulling on it. Pulling it down. With that in mind, let's lower something - someone - into water. As the person begins to enter the water, the water is displaced. It's pushed aside for the person to enter it because as a liquid, it will not support the person, cannot prevent the person from going in. But it does push back. A lot. The more the person is lowered in, the more water is displaced and the more the water pushes back. When the lowering apparatus is released after the person is all the way in the water (with the person floating), the person will have his weight supported by the water. The person "loses weight" because the water pushes back on anything put in it. The person won't feel very much of his weight, though his mass hasn't changed. Technically, the volume of water that a floating object displaces will be equal in mass to the total mass of the object put in the water. And the water pushes back on an object immersed in proportion to the force exerted by gravity on the volume of water that the object displaces. The object does not lose any mass. For objects that float, these objects are said to have buoyancy.
Water moves the boat by exerting a force on it in the opposite direction to the movement of the boat. When the propeller of the boat rotates, it pushes water backwards, which, in turn, propels the boat forward. This reaction force from the water helps move the boat through the water.
Because the object's weight pushes down on the water itself.That's why if you put in a large object inside,the water pushes itself out.
The buoyant force pushes you toward the surface.
it goes into the tube that pushes into the flange that bolts to the water pump it goes into the tube that pushes into the flange that bolts to the water pump
