Question

A company selling a type of spring makes the following claim: “The elastic potential energy that the spring is capable of storing for a given compression distance does not decrease, even after the spring compresses and/or stretches hundreds of times.” The students in a physics class have decided to test the company’s claim.
i. State a basic physics principle or law the students could use in designing an experiment to test the company’s claim

    Answer:

    Hooke’s law. Hooke’s law states that: provided the elastic limit of an elastic material is not exceeded, the extension, e, of the material is proportional to the force applied.

    Explanation:

    The appropriate law that explains the potential energy conserved by a compressed spring is the Hooke’s law. Hooke’s law states that: provided the elastic limit of an elastic material is not exceeded, the extension, e, of the material is proportional to the force applied.

    Mathematically, Hooke’s law states that:

                              F = ke

    where: F is the force applied, k is the spring constant and e is the extension of the spring.

    When a spring is compressed, its potential energy is the same as the work done by the spring.

    Potential energy = work done = \frac{1}{2} ke^{2}

    So the law that can be used to test the company’s claim is the Hooke’s law.
