Hooke's Law Spring Set Of 5, 1 Each

The Hooke's Law Spring Set Of 5 by United Scientific contains five springs with spring constants of 2.5, 4.9, 9.8, 15 and 25 N/m for comparing elastic behavior in Hooke's Law experiments. Pre-stress has been removed from each spring, and each has a hook for a weight hanger and a red arrow position indicator. Physics teachers use it for spring constant, stiffness comparison and oscillation labs. Includes an activity guide.
