Explore the physics of two carts with different masses launched by a spring! In this video, we analyze motion, forces, and energy transfer using real-world examples and clear demonstrations. Learn how ...

Dive into Part 2 of our series as we demystify the magnetic dipole–dipole force on a current loop. This video explains the underlying physics, step-by-step calculations, and practical examples to help ...

Keeping high-power particle accelerators at peak performance requires advanced and precise control systems. For example, the primary research machine at the U.S. Department of Energy's Thomas ...

During the 2026 Winter Olympics, athletes will leap off ramps, slide across ice and spin through the air. These performances will look different to my students who have studied physics through sports.

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without ...

Niels Bohr, a pioneer of quantum theory, believed that every significant challenge contains its own solution, compelling us ...

While friction isn’t the only influence on the slopes, it is definitely something at the top of a skier’s mind—especially when they’re staring down their race from the top of a very large hill.

A new theoretical study explores how activity high above Earth could subtly influence processes deep within the planet’s crust. Researchers at Kyoto University are advancing a new idea about how space ...

Gears have been around for thousands of years, with the first records dating back to 3000 BC. While they have advanced over ...

Human sperm can swim through surprisingly viscous fluids with ease – and they seemingly defy Newton's third law of motion to do so. To figure out how they slither through substances that should, in ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...
