Students will be able to
- recognize that a submerged object displaces a volume of fluid equal to the volume of the submerged part of the object,
- recognize that fluid pressure acts on all the submerged surfaces of a submerged object,
- show that the difference between the fluid pressures on the top of and on the base of a submerged object results in a vertically upward force on the object (called upthrust),
- determine the buoyancy condition for an object by comparing the weight of the object to the upthrust on the object,
- use the formula buoyant force = fluid mass displaced acceleration due to gravity.
