nciple is “upthrust”, which refers to the force acting upward to reduce the 
apparent weight of the object when it is under water. If, for example, a metal block with a volume of 
100 cm3 is dipped in water, it displaces an equal volume of water, which has a weight of 
approximately 1 N (3.5 oz). The block therefore seems to weigh about 1 N less. 
An object will float if its average density is less than that of water. If it is totally submerged, the 
weight of the water it displaces (and hence the upthrust on it) is greater than its own weight, and it is 
forced upward and out of the water, until the weight of the water displaced by the submerged part is 
exactly equal to the weight of the floating object. Thus a block of wood with a density six tenths that of 
water will float with six tenths of its volume under water, since at that point the weight of fluid 
displaced is the same as the block’s own weight. If a dense material is made into a suitable shape, it will 
float because of Archimedes’ principle. A ship floats, whereas a block of iron of the same mass sinks. 
It is also because of Archimedes’ principle that ships float lower in the water when they are 
heavily loaded (more water must be displaced to give the necessary upthrust). In addition, they cannot 
be so heavily loaded if they are to sail in fresh water as they can if they are to sail in the sea, since 
fresh water is less dense than sea water, and so more water must be displaced to give the necessary 
upthrust. This means the ship is lower in the water, which can be dangerous in rough weather.
