Explore forces with this new series that offers a full title on each type of force in order to explore the concepts in depth. Each book looks at the basis of the force, how it affects objects, and the role it plays in our lives. Everyday examples and hands-on experiments bring the subject to life, while explanatory diagrams help develop understanding of concepts and visual literacy.
