Ideal for demonstrations or hands on experiments in the physics classroom

• Use it to investigate Simple Harmonic Motion or Hooke’s Law
• 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 to 9.5 N/m

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 stainless steel wire, interfere with each other less than those of a helical spring, making the motion truly sinusoidal. The spring constant for this 7 inch long spring will vary between 9 to 9.5 N/m
