A medium-stiffness spring (k = 200.00 N/m) stores 0.2500 J of elastic energy at this displacement.

  • A spring constant of 200.00 N/m means the spring requires 200.00 N of force per m of compression or extension.
  • At a displacement of 0.0500 m, the spring exerts a restoring force of 10.0000 N.
  • The elastic potential energy stored is 0.250000 J. Doubling the displacement would quadruple the stored energy, since PE grows with x squared.

Next stepTo find the oscillation period of a mass on this spring, use T = 2pi sqrt(m/k) in our Simple Harmonic Motion calculator.
