How Much Energy is Stored in Your Coil Spring? | GlobalSpec

Now that the spring constant is known, the potential energy can be calculated using the formula above. If the spring in the example above is extended 20 mm from the equilibrium position, the potential energy can be calculated as follows: PE = 1/2kx2. PE = 1/2(490.5 N/m) (20 mm)2. PE = 1/2(490.5 N/m) (0.02 m)2.
