Coil Spring, 74 mm

This 74 mm coil spring is well suited to experiments with elastic oscillations. It has a diameter of 11 mm and a spring constant of about 3.2 N/m, which makes it suitable for investigating Hooke's law and the motion of spring systems, and it is designed for repeated use, including in teaching. In physics lessons it can be used to demonstrate elastic forces, with pupils investigating the relationship between force, extension and spring constant, and it can be included in experiments on harmonic oscillation, energy conversion and damping, giving a concrete introduction to both mechanical oscillations and more general wave phenomena.
