Eisco Labs Harmonic Motion Spring, 7 inches

Eisco Labs Harmonic Motion Spring

This large spring is ideal for demonstrations or hands on experiments in the physics classroom. Use it to investigate Simple Harmonic Motion or Hooke's Law.

The Harmonic Motion spring's elongations are closely proportioned to the applied forces, making it easy to use. The windings of this truncated cone, made of spring brass wire, interfere with each other less than those of a helical spring, making the motion truly sinusoidal.

The spring is 7 inches (18 cm) long with a maximum diameter of 1.4 inches (3.5 cm) and a spring constant (k) of 9.6 N/m.
