It is the force that causes wood and boats to float in water and the reason why objects feel lighter when submerged in water. In a gravitational field, the pressure at the bottom of a fluid is higher than at the top (because of the weight of the fluid above it, as in air ... WebSep 28, 2024 · Buoyancy is the force that enables boats and beach balls to float on water. The term buoyant force refers to the upward-directed force that a fluid (either a liquid or a gas) exerts on an object that is partially or completely immersed in the fluid. Buoyant force also explains why we can lift objects underwater more easily than on land. bai case
