Genaral information on “Impulse”
This is explained by the law of action and reaction. When the fly climbs up the glass, the balance is pushed out of equilibrium for a moment by the force involved in climbing. However, if the fly hovers at a constant level, the balance reaches equilibrium again as a force equal to the weight of the fly acts on the balance via the air.
