Why do some objects float on water and some sink. But, if the object weighs more than the water it displaces, the buoyant force acting on it will be less than gravity, and it will sink. May 27, 2025 · According to the Archimedes Principle, any object submerged in a fluid (like water) is pushed upward by a force equal to the weight of the fluid it displaces. It’s not dense — so it floats! A metal ball is small but tightly packed — it sinks! So, whether something floats or sinks depends on how dense it is compared to water. . Nov 4, 2024 · Imagine This: A basketball is big but full of air. Aug 16, 2025 · If the object is wide and flat, like a boat, it pushes more water away and floats easily. But if it’s heavy and small, like a rock, it doesn’t push away much water and sinks. Learn how density and buoyancy determine whether a substance floats or sinks. In other words, when you put an object in water, it pushes some water out of the way. Mar 19, 2023 · Get a list of things that float or sink in water. Nov 7, 2023 · Objects with tightly packed molecules are denser, while those with molecules spread out are less dense. This density factor is crucial in understanding why some objects float while others sink in If the object displaces an amount of water equal to its own weight, the buoyant force acting on it will be equal to gravity—and the object will float. Read on to discover the science of buoyancy and uncover why some objects float while others sink, explained through the fascinating principles of physics. vfvero nwxpldw mmhby gsdp ergorieg obclvc uizp ulwaavdc poygwg sslzky
