what is buoyant force?Explain with examples.
Answers
Answer:
The buoyant force comes from the pressure exerted on the object by the fluid. Because the pressure increases as the depth increases, the pressure on the bottom of an object is always larger than the force on the top - hence the net upward force. The buoyant force is present whether the object floats or sinks.
Example - The atmosphere is filled with air that exerts buoyant force on any object. A hot air balloon rises and floats due to the buoyant force. It descends when the balloon's weight is higher than the buoyant force. It becomes stationary when the weight equals the buoyant force.
Whenever an object is immersed in a liquid it experiences an upward force that force is know as Buoyant Force...
eg :- we are able to swim due to buoyancy force.
