Question

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?

Answer 1

-it is because force is acted against gravity by the spring when we keep the mass on it
-it depends upon the spring constant
-i will answer it later!!
