submarine is a vessel that can float on surface and swim under water just like any fish do. If you want to know how it works then take a plastic water bottle, empty it and place it on water - it will float. Now fill a little amount of water and you will notice that it is going down inside water. It is all on ratio of water and air inside the volume of water bottle. Same is in case of submarine. It has dedicated tanks that will fill up with water to sink itself under water and remove the water to surface. It maintains the ratio(of water to air) to stay in a position under water.

Very well said @nethan i would give an example of balloon. Let's say if balloon is filled with surrounding air, then the balloon will come down due to the weight of rubber. Balloon is filled with lighter weight then air then it will start floating and move in upward direction. The same happens with submarine, it's a balloon filled with water the it will start to sink and if filled with lighter weight then water, it'll start to float. The ratio of water to air maintains its position under water.
