Question

A student hangs a 0.125 kg object on a spring, sets it into oscillation, and obtains the data for the position and velocity of the object as a function of time shown in the graphs below. Next the student is given a rubber band and asked to determine whether the relationship between the restoring force exerted by the rubber band and the amount it is stretched is the same as that of an ideal spring. (c) Describe an experimental procedure that the student could use to collect the necessary data, including all the equipment the student would need. (d) How should the student analyze the data to determine whether the relationship between the restoring force exerted by the rubber band and the amount it is stretched is the same as that of an ideal spring? What evidence from the analysis would be used to make the determination?

Explanation / Answer

c. The equipments required are:

i. rubber band

ii. 0.125 kg object

iii.a scale

iv. stop watch

Steps or procedure to follow:

Make rubber band hang freely. Then attach the object to the rubbser band and held it with hand so that no stretching takes place. Then with the help of stop watch, the positions need to be noted at different intervals.

d. the student should try to plot a graph between position and time and if the relationship is a repeating cycle like that of a spring, then it can be concluded that the same relationship exists in case of a rubber like that of spring between restoring force and displacement.
