Can heavy objects float on water?

Yes, heavy objects can float on water if they displace a sufficient volume of water based on their shape and density. According to Archimedes' principle, an object will float if the weight of the water it displaces is greater than or equal to its own weight. For example, large ships are designed with hulls that displace enough water to support their weight, allowing them to float despite being very heavy. Conversely, smaller heavy objects, like a rock, will sink because they displace less water than their own weight.
