SHM Model - MOS

The figure to the right shows part of a system consisting of a bob hanging from a light spring which is located on Earth. You wish to experimentally determine how to change the frequency of the mass oscillating on the spring.

(a) Describe the experimental procedure that you would use. In your description, state equipment you would use, the measurements you would make, how you would use the equipment to make them and how you would determine the frequency from those measurements.

(b) You next wish to discover which parameters of a mass on a spring affect its frequency. Indicate one parameter of the given mass / spring system that could be varied. Describe how you would conduct the experiment, and indicate how you would analyze the data to show whether there is dependence. Justify your answer.

(c) One skill to focus on during this data collection opportunity is how to identify possible sources of error in your data collection. While collecting data, closely examine how you could work to eliminate the system or random error in your data. 

The figure below shows a system consisting of a cart on a frictionless surface between two springs of equal strength. You wish to experimentally determine how to change the frequency of the cart oscillating between the springs.

(a) Describe the experimental procedure that you would use. In your description, state equipment you would use, the measurements you would make, how you would use the equipment to make them and how you would determine the frequency from those measurements.
