Everything in the universe is on the move! Motion plays a big part in our world, even when we cannot see or feel it. Young readers will discover the laws of motion and learn how they affect everything we do. From the action of sports to the thrill of amusement park rides and from the movement of the planets to the motion of the waves, students will learn why things speed up, slow down, change direction, or stop. This book introduces the revolutionary ideas of scientists such as Isaac Newton and Galileo and shows how science applies to everyday events.
