This set consists of 5 springs with different spring constants. The forces required for a 2 cm extension are 0.5N, 1N, 2N, 3N and 5N, respectively. Pre-tension is removed for accurate results. The lower part of the springs is made with hooks to support the weights. There is also a red plastic arrow to indicate the location.

What is Hook’s Law?

Hooke’s law is the law that explains that the decay of a substance is approximately directly proportional to the force causing the decay. Substances that obey this law are called linear elastic materials. Hooke’s law is named after the 17th century English physicist Robert Hooke. Hooke published his law with a Latin anagram in 1670, and gave its solution in 1678: Ut tensio, sic vis (in Turkish meaning The more elongation, the more force) In systems that comply with Hooke’s law, the amount of extension is linearly dependent on the weight.
