Buoyant Force

1.Meaning:The thrust force acting on an object that is floating on the
surface of a fluid.

2. Actual weight: weight of an object in the air

3.Apparent weight: weight of an object immersed in fluid

Buoyant force = actual weight – apparent weight

4. An object will float on water if the buoyant force acts on it is enough to
support its weight.

5. Buoyant force is a force that acts on the object when the object
completely submerged in water.
