Detailed Book Description
What are the forces behind projectiles? Why do rocks and rockets soar through the air in an arch?
The game is on the line. You crouch, you shoot—will the ball go in the basket?
You might think that nailing a three-pointer is just luck, but there are many forces at work that determine if you’ve made a game-winning shot. In Projectile Science: The Physics Behind Kicking a Field Goal and Launching a Rocket with Science Activities with Kids, readers ages 10 to 15 learn why projectiles follow the paths they do. Young learners who are fascinated with potato cannons, slingshots, and rocketry will love taking that next step and applying what they learn about the laws of physics to the science of figuring out where to aim. In this book, readers learn about the forces that act on the projectiles and how to calculate those forces to make educated predictions about where their homemade rockets and other projectiles will land.
Essential questions that promote critical examination of the science, primary sources, online videos, and science-minded engineering activities let readers have a blast learning about the physics of ballistics!
