Lesson: Hooke’s LawPhysics
In this lesson, we will learn how to use F = kx (Hooke’s law) to find the force constant of a spring and find the force exerted by a spring at a given compression.

In building a house, carpenters use nails from a large box. The box is suspended from a spring twice during the day to measure the usage of nails. At the beginning of the day, the spring stretches 50 cm. At the end of the day, the spring stretches 30 cm. What percentage of the nails have been used?
Two identical springs, each with the spring constant 20 N/m, support a 15.0 N weight, as shown.
What is the tension in spring ?
What is the amount of stretch of spring from the rest position?
A man with a mass of 80.0 kg stands on a pogo stick, compressing the spring in the stick by 0.120 cm. What is the spring’s force constant?
