Force and motion are all around us and help us move and do great things! Through a variety of vivid images and stunning facts, readers will explore how forces and motions work. The easy-to-read text and accessible glossary and index ensure that readers have the tools they need to understand such concepts as gravity, equilibrium, acceleration, deceleration, electromagnetic fields, pressure, kinetic energy, and inertia. To gain further insight into how gravity, forces, and motion works, a stimulating lab activity is featured!

Forces and motion are at work all around you—when you kick a ball, ride a bike, or drop a book. But what exactly are forces? And how do they make things move? For thousands of years, scientists have been testing hypotheses about forces and motion and learning from the results of their experiments. These lead to more questions: Why do you speed up when you're biking down a hill? Why are heavier objects harder to pull? Why doesn't the moon float off into space? The answers may surprise you! Find out how forces and motion are at play with everything on Earth and beyond.
