Apparent weight is a property of objects that corresponds to how heavy an object is.
The apparent weight can differ from weight when an object is "partially or completely immersed in a fluid", where there is an "upthrust" from the liquid that is working against the force of gravity.
Another example is the weight of an object or person riding in an elevator. When the elevator begins rising, the object begins exerting a force in the downward direction(opposite direction).
this downward force results in, changing the apparent weight.
