Hooke's Law Apparatus

This Hooke's Law Apparatus is used to demonstrate that the relationship between the extension on a spring is proportional to the load applied to it. This complete apparatus has a 15 cm adjustable scale, marked in millimetres, to mitigate parallax error. The scale is mounted on sturdy 30 cm support rod and a wooden base. A hook supporting a coiled spring with a 10 g mass hanger and indicator is attached to rod. Nine additional 10 g slotted masses are included, for a total of 100g. Includes instructions.
