Oscillating masses on springs or rubber bands (what is the spring constant?)

Report As part of PHYS1110 you need to produce a report about the physics behind an everyday phenomenon of interest to you. As part of this report you will need to construct an investigation that demonstrates the physics behind the phenomenon.

In order to help you produce the best possible report there are four parts to this task.

Before 9 PM on 06/05/18 you need to make a post on your group discussion forum about the topic you plan on doing for your final report. The post needs to include your Aim, a brief method and identify the dependent and independent variable(s) in your experiment as well as any variables you intend to keep constant. Your tutor will give you feedback to help you improve your plan. This post will contribute 1% of your mark for the subject.

You will need to submit this report to your peers for marking on 13/05/181 at 09:00 PM. Your peers will provide you with feedback that you can use to improve your report before submitting the final version. You will be required to give feedback to five of your peers (9% of your final mark for this subject will come from the quality of the feedback you give your peers and the completeness of the report you submit). You will then submit the final version of your report through Turnitin by 03/06/18 (at 09:00 PM), to be marked by your tutor. This mark will form 20% of your final mark for the subject.

Some phenomena that you may be interested in investigating are listed below. Remember that you will need to be able to come up with equations and a practical investigation in order to investigate some aspects of your chosen phenomenon:

• The melting of the north pole (what is the latent heat of water?) • Oscillating masses on springs or rubber bands (what is the spring

constant?) • The greenhouse effect • Skate-boarding • Different objects rolling down slopes (what effect does rotational motion

have?) • Bouncing balls • How the eye works (you could consider how we view light of different

intensities, or how the eye works as a lens) • How does a pulse oximeter work (this may be hard to investigate unless

you have access to relevant equipment, such as a pulse oximeter app on a smart phone), you will need to concentrate on the physics

1 Note: due to the way the peer review tool works it is not possible to get an extension on this deadline. Please be very careful not to miss it as if your report is not uploaded at this time you will not be able to take part in the peer review exercise and so will not get 9% of the marks for this course.

• How do boats sail into the wind? • How does your favourite musical instrument work?

There are a few topic you may not choose: • Any of the topics covered in the investigations ie:

o The specific heat of water o Measuring coefficients of static friction (kinetic friction is fine) o Measuring the speed of sound with resonance in tubes (other

methods are fine) o Measuring the refractive index of water

• The three topics covered in the sample reports: o Measuring acceleration due to gravity with a pendulum o Measuring the pressure when brewing by using the height a liquid

rises up a tube o Modelling Fohn winds with thermometers in the bathroom

Some things to keep in mind when you are choosing your topic:
