Question

buoyancy is an upward force experienced by an object that is less dense than the fluid it is in. buoyancy and gravity work in opposite directions. gravity pulls an object down and buoyancy pushes an object up. objects that are less dense than water float and objects that are more dense than water sink. choose the correct answer. which is the best definition of buoyancy? upward force exerted by fluids force that opposes the motion of an object force of attraction between all matter

Explanation:

Answer:

upward force exerted by fluids
