The plot is shown below.Ī linear regression analysis yields the following statistics: The data table below shows some representative data for such an experiment.īy plotting the force-stretch data and performing a linear regression analysis, the quantitative relationship or equation can be determined. A regression analysis of the force-stretch data could be performed in order to determine the quantitative relationship between the force and the amount of stretch. The force which is applied in each instance would be the weight of the object. For each object which is added, the amount of stretch could be measured. To determine this quantitative relationship between the amount of force and the amount of stretch, objects of known mass could be attached to the spring. Exactly what is the quantitative relationship between the amount of pulling force and the amount of stretch? And if you were to pull with a much greater force, the spring would stretch a much greater extent. If you were to pull with just a little force, the spring would stretch just a little bit.

If you were to hold the bottom of the spring and pull downward, the spring would stretch. The spring hangs in a relaxed, unstretched position.

Consider the system shown at the right with a spring attached to a support. We will begin our discussion with an investigation of the forces exerted by a spring on a hanging mass. Such quantities will include forces, position, velocity and energy - both kinetic and potential energy. Now we will investigate the motion of a mass on a spring in even greater detail as we focus on how a variety of quantities change over the course of time. The mass on a spring motion was discussed in more detail as we sought to understand the mathematical properties of objects that are in periodic motion. In a previous part of this lesson, the motion of a mass attached to a spring was described as an example of a vibrating system.
