What happens to an object that weighs more than water when placed in it?

When an object that weighs more than water is placed in it, the object will sink. This phenomenon is explained by the principles of density and buoyancy. An object sinks if its density is greater than that of the fluid it is placed in, which, in this case, is water. Since the object weighs more than water, it displaces a volume of water that is less than its own weight, leading to a net downward force that causes it to sink.

In contrast, an object that floats has a density less than that of water, while an object that bobs up and down or remains suspended would involve different dynamics related to buoyancy and water displacement based on precise balances of weight and buoyant forces, which do not apply here since the weight is greater than that of water.
