This core mechanics text is suitable for use with any A- or AS level mathematics course. Completely self-contained, it combines four units from the SMP 16-19 series: Newton's laws of motion, Modelling with force and motion, Modelling with circular motion and Modelling with differential equations. The material has been adapted to present a logical and approachable development of the subject, with a strong emphasis on the development of the laws of mechanics from experimental results. The text includes frequent 'development' sections which give students the opportunity to explore and expand their own understanding of the material as they progress through the book. The single volume format should appeal particularly to sixth form and Further Education colleges and international schools.
