The Physics Classroom » Physics Tutorial » Vibrations and Waves » Motion of a Mass on a Spring

In a previous component of this lesson, the activity of a mass attached to a spring was described as an instance of a vibrating device. The mass on a spring motion was questioned in even more detail as we smust understand the mathematical properties of objects that are in periodic activity. Now we will certainly investigate the movement of a mass on a spring in also higher information as we emphasis on exactly how a range of quantities readjust over the course of time. Such amounts will certainly encompass forces, position, velocity and also energy - both kinetic and potential energy.

### Hooke's Law

We will certainly start our discussion via an examination of the forces exerted by a spring on a hanging mass. Consider the mechanism presented at the right with a spring attached to a support. The spring hangs in a peaceful, unstretched place. If you were to host the bottom of the spring and pull downward, the spring would stretch. If you were to pull through simply a small pressure, the spring would certainly stretch simply a little little. And if you were to pull through a much better pressure, the spring would certainly stretch a a lot greater extent. Exactly what is the quantitative connection in between the amount of pulling pressure and also the amount of stretch?

To identify this quantitative connection in between the amount of force and also the amount of stretch, objects of known mass might be attached to the spring. For each object which is added, the amount of stretch could be measured. The pressure which is used in each instance would be the weight of the object. A regression analysis of the force-stretch data could be perdeveloped in order to determine the quantitative partnership between the force and the amount of stretch. The information table listed below reflects some representative data for such an experiment.
