Editing Weight (section)

=== Apparent weight ===
{{Main|Apparent weight}}

In many real world situations the act of weighing may produce a result that differs from the ideal value provided by the definition used. This is usually referred to as the apparent weight of the object. For instance, when the gravitational definition of weight is used, the operational weight measured by an accelerating scale is often also referred to as the apparent weight.<ref>{{cite journal
