the name of a boat that goes underwater is called a SUBMARINE.
U = Unter (in German) = under so is a boat that goes under (the water) namely a submarine
Boats displace water (push it out of the way). The boat weighs less than the water it displaces, so it floats on top. If the boat weighed more than the water is displaces, it would sink- which is how a submarine goes under water.
The force which resists the motion of a boat when it goes through the water.
A subarine and a boat, ship.
The part of a boat that is under water has the same volume as the amount of water that weighs the same as the boat and everything in it. That is why a boat goes lower into the water whenever somebody boards. Propulsion is acheived by taking advantage of Newton's third law of motion: for every action there is an equal and opposite reaction. To move the boat in a certain direction, water is pushed in the opposite direction. Most boats use a propeller to push the water, but it can also be pushed by oars, a water wheel, a jet, etc.

No it depends on its dynamics and the air in the boat that's why when water goes into the boat it sinks a boat could be 1 kg or 1000 tonnes.
This actually happened with Titanic. The only way the boat can sink is if the boat has a giant hole in it. A boat floats on water, but what happens is the water from the ocean or lake or whatever goes into the boat. As the water fills up the boat, the boat justs get very heavy. and it goes down deep in the water.Example: The titanic hit an iceberg and it made huge holes on the side of the boat. So water went in the basement and It the water went up to every floor and boat got so heavy. And when the boat was rising up it go SO heavy that it snapped in halfexample: Also a rock can sink. when you throw a rock in the water it sinks because the rock is soooo heavy
I live on a lake and swim quite often. When you go underwater and a boat goes by a 1/4 mile away, you can distinctly hear the prop and engine whirring. Also, the boat sounds much closer and louder than it does above water because sound travels better in water than in air. This is because it is more dense than air.
what is the prefix root of the word hydroplane
"unterseeboot" : boat that goes under the sea = submarine
When a boat is floating on water it displaces water equal to its weight(Archimedes Principle). As the density of water is less than boat so water displaced is greater than volume of boat. When the boat sinks water displaced is equal to volume of boat. So less water is displaced in 2nd case and consequently water level goes down. Note - relation between volume(v) mass(m) and density(d) : d = m/v
