Nov 9, 2013 ... If I lift a box vertically, why is the work I do equal to the distance I lift it times the
force of gravity on the box? [duplicate] ...
•How much energy is required to do work? ... ➢Work is done to raise the box
vertically against the force ... The work required to lift an object equals the object's
When you lift a box up off the floor, you must exert a force at least equal to the
weight of the box. If you lift the box at constant speed, you "do work" on the box
Apr 29, 2008 ... I am reading Principles of Physics by Serway and Jewett, and it has an example
of a person lifting a box vertically. It states that the work done ...
