What is your opinion on Physics? Is it hard? Do you regret taking it? Would you have rather taken Anatomy? I have to choose either Anatomy or Physics and I thought who better to ask than people who have taken or are taking Physics.

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?
