Coil Spring, 27 / 155 mm

This coil spring is intended for experiments with elastic oscillations. It has a diameter of 27 mm, a length of 155 mm and a spring constant of about 4.7 N/m. In physics lessons it can be used to investigate Hooke's law and the relationship between force and extension, and it is equally well suited to harmonic-oscillation experiments in which pupils measure oscillation times, calculate spring constants and analyse the energy conversion between potential and kinetic energy.
