APFIVE Potential Energy of Springs in Series
Two identical springs, each with a spring constant k, are connected in series. How does the potential energy stored in this system when it is displaced by a distance x from equilibrium compare to the potential energy stored in a single spring with constant k displaced by the same distance?
A

B
Twice as much potential energy
C
Equal potential energy
D
Half as much potential energy
