The answer is Newton's Laws of Motion, and this book makes all three crystal clear for curious kids ages 7–12. Why do rockets blast off, seatbelts save lives, and skateboards push back when you jump — and what do they all have in common? Through real-world examples, plain-English explanations, and chapter-by-chapter deep dives, young readers will discover how invisible forces shape everything they see, touch, and experience every single day. Inside this book, kids will explore: Newton's First Law — why objects keep moving (or stay still) until a force acts on them, and how seatbelts use inertia to protect you Newton's Second Law — how force, mass, and acceleration are connected, and why a bigger push moves things faster Newton's Third Law — every action has an equal and opposite reaction, from rocket launches to jumping off a skateboard Momentum — what happens when mass gets moving and why it's hard to stop
