Forces and motion - Chris Oxlade

This practical book answers common questions about forces and motion by looking at evidence and demonstrating their properties through a range of carefully chosen experiments that can be done in the classroom or at home. It covers such questions as 'What are forces?', 'Why do things fall downwards?', Why do things start moving?', Why do things move in circles?', ''How do we measure forces?' and 'What is pressure?' It also includes questions for readers to investigate further on their own.
Written by a highly experienced and acclaimed science writer, the book includes links to useful websites as well as glossary, index and list of further reading.
