First Law

Synopsis
Explores the first law of thermodynamics in terms of the energy inputs and outputs of a particular device, the hydraulic ram. The idea of perpetual motion machines is a fantasy, but it is used here to cue how a careful measure of the energy inputs and outputs of a machine can give the effectiveness of the device as an energy converter.

Notes
NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
