Elastic Potential Energy Calculator (Ep=½kx²)

Favorite

Compute elastic potential energy via Ep = ½kx²: enter stiffness and deformation to get joules and the maximum release velocity.

Key points

Elastic Potential Energy Calculator (Ep=½kx²): Compute elastic potential energy via Ep = ½kx²: enter stiffness and deformation to get joules and the maximum release velocity. Formula: Ep = ½·k·x². Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Ep = ½kx²: stored elastic energy scales with the square of deformation; unit J. Energy transfer: on release, elastic energy converts to kinetic energy, maximum velocity v = √(2Ep/m) (ignoring friction and spring mass).

Engineering notes

  • Ep = ½kx²: stored elastic energy scales with the square of deformation; unit J.
  • Energy transfer: on release, elastic energy converts to kinetic energy, maximum velocity v = √(2Ep/m) (ignoring friction and spring mass).
  • Real springs have damping and friction, so efficiency < 100%; energy-storage mechanisms (mainsprings, shock absorbers) are often estimated this way.
