Where force (F) is the result of a change in acceleration (a), generated against a mass (m) or the weight of the barbell. Since generally all snatches and cleans from the platform to receiving the weight are achieved in about 1 second, then acceleration (a) is constant, and force (F) will be in equilibrium with that mass...
