Observing Forces Of Motion

Observing Forces Of Motion

When something moves, a lot is going on that we don’t see. But we can make deductions based on our observations of different movements! Try moving different objects on different surfaces and see what you learn.

Build a Shaduf

Build a Shaduf

From Engineering

Ancient farmers used a long wooden lever called a shaduf to lift water from rivers to irrigate crops and for other uses. This simple tool was incredibly effective at making it easier to move water. In this activity, you'll harness the power of a lever as you design and build a working model of a simple shaduf.

Reviews

“Accurately aimed at its intended audience and complete with vivid and informative graphics, Projectile Science is an extremely readable yet factually accurate account of mechanics and its applications to projectiles.”

—Ramamurti Shankar, John Randolph Huffman Professor of Physics, Yale University

“Packed with interesting facts; sure to engage its audience.”

—Nino Polizzi, BSEE, engineering instructor, Samueli Academy

“An interesting way to make classical motion concepts relevant to young readers.”

—Vince Huegele, committee chairman, National Association of Rocketry Education University School

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!
