Discover how Newton’s First Law, or the Law of Inertia, explains everyday motion—why objects stop, when they keep going, and how friction plays a role. Learn with relatable examples like sliding books, parked cars, and ice skaters.

It's been called "the Queen of Sciences"--mathematics. It might not be as obvious in Olympic sports as physics or materials-engineering, but math--from simple arithmetic to calculus--is part of every jump, every spin, every move the...

Join us as we delve into the physics that make figure skating possible. From pirouettes to acrobatic lifts, learn how skaters like Sarah Abitbol utilize principles such as angular momentum and the gyroscopic effect to perform stunning...

If you stick water in the freezer, it will take a few hours to freeze into ice. How is it, then, that cold packs go from room temperature to near freezing in mere seconds? John Pollard details the chemistry of the cold pack, shedding...

Why does the Earth spin? Does a basketball falling from a spinning merry-go-round fall in a curve, as it appears to, or in a straight line? How can speed be manipulated while spinning? In short, why is the spinning motion so special?...

In this video, students will learn about six simple machines: lever, inclined plane, wedge, wheel and axle, pulley, and screw. They will understand the basic principles of how these machines work and how they can make our lives easier by...

• Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe. • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the...
