Elastic Potential Energy - Stretching of a spring

• What you want to calculate

  Spring Potential Energy(U) Spring Force Constant(k) Spring Stretch Length(x)

• Spring Force Constant(k)

  N/m

• Spring Stretch Length(x)

  m

• Spring Potential Energy(U)

  J

•  

Formula:
Spring Potential Energy:


Spring Force Constant:


Spring Stretch Length:


where,
U = Spring Potential Energy,
k = Spring Force Constant,
x = Spring Stretch Length.

Elastic potential energy is the energy stored in compressed or stretched objects, elastic potential energy is used in calculations of mechanical equilibrium.
