Learning about heavy physics concepts can sure weigh down your brain! You need to understand huge forces (like gravity, magnetism, and inertia), huge speeds (light moves at 670,615,200 miles per hour), and even huger mysteries (what space-time is). How can all these big numbers and concepts make more sense? Infographics! The charts, maps, and illustrations in this book tell a visual story to help you better understand key concepts about forces and motion. Crack open this book to explore mind-boggling questions such as: • How do spaceships break away from Earth''s gravity? • Why don''t submarines and ships sink in water? • What keeps riders from falling out of roller coasters (besides their safety belts!)? The answers are sure to stick with you!
