This book looks at supersonic flight. The shock boundary caused by the abrupt change in pressure is explained with the aid of a diagram. The development of supersonic aircraft is explored, with a look at the overall efficiency of supersonic flight compared to subsonic flight. The effect of kinetic heating from air molecules…
This publication, from the Technology Enhancement Programme (TEP), looks at the topic of flywheels and how they can be used to store or smooth energy flows. The book initially provides information for students on the following topics: • The energy-storage system • Cyclicity of supply • Energy and system energy…
This Schools Council Integrated Science Project (SCISP) topic book was written to accompany the third of the SCISP students’ manuals. Contents • The beginnings of the railway • The railway's competition • Motive power • Inter-city travel • Electrification: the technical aspects •…
This publication, from the Technology Enhancement Programme (TEP) explains how a generator converts mechanical energy into electrical energy. To understand how this happens, students need to know something about magnetic fields and what happens when a conductor such as copper wire is moved within a magnetic field. The booklet…
Work done in this Nuffield 13 - 16 module followed from the S unit called ‘Rockets and momentum’. This S unit provided enough material for eight double periods during a single-certificate science course. The teachers’ guide included eight worksheets to supplement the students’ booklet. The general notes…
From the Science and Technology Facilities Council (STFC), the 'Big questions, big experiment' wall chart describes the Large Hadron Collider (LHC) at CERN. It looks at the "big questions" about our Universe that scientists are trying to answer, and how the amazing LHC will help them to do so. The 'Tunnel…
