This tag is for the classical concept of forces, i.e. the quantities causing an acceleration of a body. It expands to the strong/electroweak force only insofar as they act comparable to ‘classical’ forces. Use the [particle-physics] tag for decay channels due to forces and [newtonian-mechanics] or one of the other subtopics of [classical-mechanics] for the dynamics of classical systems.

How does the normal force change *while* I'm lifting a heavy object?
A heavy weight is resting on a surface with, with the normal force equal to the weight. So the object is stationary. (W = N)
Now I try to lift the heavy object so I'm exerting some upward force U. Th …
