Buoyant force is an upward force exerted by a fluid on an object in the fluid. It opposes the weight of the object and is responsible for making objects float. Two examples of buoyant force are the floating of a ball in water and the floating of a helium-filled balloon in the air.
Buoyant force is an upward force exerted by a fluid on an object in the fluid. It opposes the weight of the object and is responsible for making objects float. For example, when you put a ball in water, the buoyant force pushes the ball upwards, causing it to float. Similarly, when a helium-filled balloon is released into the air, the buoyant force pushes it upwards, allowing it to rise.
