Consider an object freely falling under gravity in a viscous fluid. Choose all true statements. Even though gravity is pulling the object down, the net acceleration of the object is zero after it reaches terminal speed. As the object reaches terminal speed, the drag force on the object is zero. All forces acting on the object are in perfect balance at terminal speed. The net force acting on the object is not balanced until the object reaches terminal speed.
