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.

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!

Easy to duplicate, [these experiments] demonstrate the intended principles and encourage critical thinking.

Everything moves! Kids run around the playground, cars drive on the road, and balls fly through the air. What causes all this motion? Physics! Forces and motion rule the way everything moves through space. In Explore Forces and Motion! With 25 Great Projects, readers ages 7 through 10 discover that the push and pull of every object on the planet and in space depends on how a force acts upon it. Things float because of a force called buoyancy, we stick to the ground because of a force called gravity, and we make footprints in sand because of a force called pressure. Physics becomes accessible and interactive through activities such as a experimenting with a water cup drop, building a bridge, and spotting magnetic field lines. Simple machines such as levers, pulleys, and wedges are used as vehicles for discovery and comprehension of the foundational concepts of physical science. Using a theme familiar to everyone—motion—this book captures the imagination and encourages young readers to push, pull, twist, turn, and spin their way to learning about forces and motion.

Illustrated throughout, this is an introductory text on dynamics which will be of interest to children aged from six to nine.
