We have an analogy between circular motion and SHM that we can use to describe SHM mathematically. But in order to ensure that black cylinder rotates with exactly the right angular velocity \omegaω so that its motion syncs up with the side to side motion of the glider, there must be some relationship between \omegaω and the properties of the glider/spring system. The goal of this section is to find the fundamental relationship.

1.Draw a force diagram for the glider attached to the spring at any point in its motion. Then write down Newton's second law for the glider. Keep it in a general algebraic form.

2. Substitute the expressions for x(t) and a(t) that you found in the previous sections into the Newton’s second law equation you came up with above. Then simplify the equation to come up with an expression for \omegaω that is necessary for the equation to be true. Record all your work in the text box below.

a) Use Newton’s second law to set up an equation that describes the motion of a mass moving horizontally under the influence of a linear spring force. Neglect air resistance and friction. Solve your equation to obtain expressions for the object’s position, velocity and acceleration as functions of time. Obtain an expression for the angular frequency of the oscillation. Clearly define all quantities you need to do this. b) Repeat a) using energy ideas.

Finding the Spring Constant We can describe an oscillating mass in terms of its position, velocity, and acceleration as a function of time. We can also describe the system from an energy perspective. In this experiment, you will measure the position and velocity as a function of time for an oscillating mass and spring system, and from those data, plot the kinetic and potential energies of the system. Energy is present in three forms for the mass and spring system....
