If the net force acting on a moving object is zero, the object will: * slow down and, eventually, stop.
continue at the same speed but change direction.
O
continue in the same direction but change speed.
O
continue in the same direction with no change of speed.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
