Learning outcomes

This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates

On completion successful students will be able to:

  1. use the method of dimensions to help solve problems in physics
  2. use orders of magnitude and estimations 
  3. describe and explain the physics basis of various everyday atmospheric phenomena
  4. describe and explain the physics underlying various aspects of the human body, including sight and hearing 
  5. discuss how physics can be applied to sport
  6. explain the physics behind a number of devices in modern technology
