The forces at work in buoyancy. Note that the object is floating because the upward force of buoyancy is equal to the downward force of gravity. In science, buoyancy ( /ËbÉÉª.Énsi, -Éntsi/ or /ËbuËjÉnsi, -jÉntsi/;) or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.
What is Buoyancy? Boats, canoes, ships, kayaks, and rafts all have one thing in common- they are used for transport on seas and rivers, because they float. Itâs easy to figure out that if they are made out of wood they will float, because wood floats in water. However, when you see a huge cargo ship or a cruise-liner that looks like a floating building on the water, you canât help but wonder why this massive chunk of metal doesnât sink.
