PRACTICE / Elastic potential energy

Energy in a series spring pair

Two 100 N/m springs are joined in series. The total extension is 0.20 m.

Find the total stored elastic energy.

Organize the givens & assumptions
  • k₁ = k₂ = 100 N/m
  • xtotal = 0.20 m

Two ideal linear massless springs in series; same tensile force, total extension 0.20 m.
