  • Diameter: 2cm
  • Ideal for school science classes demonstrating Hooke`s Law with metal spring and weight.
  • Extension spring is helical wound coils, wrapped tightly together to create tension.
  • Extension springs have hooks, loops, or end coils that are pulled out and formed from each end of the body.
  • Spring extend as you apply force to them, pulling apart the coils.
  • Resistance against this force stores mechanical energy within the coil.
  • When you remove the force, the spring releases its mechanical energy by snapping back into its original state with no pitch between coils.
