What is dynamic equilibrium in laymen's terms?

  1. Jul 8, 2015 #1
    I was receiving help for the following problem...

    The 2.0 kg wood box in the figureslides down a vertical wood wall while you push on it at a 45 ∘ angle. The coefficient of kinetic friction of wood on wood is μk = 0.200. What magnitude of force should you apply to cause the box to slide down at a constant speed?

    And I was told to set the F(net) of the y-axis to 0 because the box is in dynamic equilibrium.
    What exactly does dynamic equilibrium mean? I want to understand so I'll know to use it in a different problem.

    Dynamic equilibrium means no accelerations, even though the box is moving.

    The sum of the forces in each direction should be zero.
