1. Is work of a spring the same as the potential energy of a spring? U = .5kx^2? 2. Do springs have a kinetic energy formula? If so, what is it? 3. Work is the same as energy right? Because work and energy are both in joules, right? work = fdcostheta = kgm^2/s^2 = newton meter = joule energy: kinetic energy = 1/2mv^2 = kgm^2/s^2 = newton meter = joule potential energy = mgh = kgm/s^2m = newton meter = joule Thank you for your help.
