In this engaging title, young readers learn about different forms of energy! Different forms of energy such a potential and kinetic are explained, as are gravity, acceleration, velocity, g-forces, and centripetal force. These properties are illustrated by the design and operation of roller coasters. Colorful infographics make joules and shifting energy easily accessible, and prominent contributors such as LaMarcus Thompson are featured. A fun experiment with potential and kinetic energy brings the science of energy to life! Aligned to Common Core Standards and correlated to state standards.
