You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

"Join me as we dive into the core concepts of forces and motion! In this video, we’ll review Newton’s Laws of Motion, explore how forces affect objects, and break down key principles like acceleration ...

Why do things fall? It’s about force and motion. Find out more in this Science Trek short. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. On this ...

Find out how forces and motion make our world move in the Science Trek: The Web Show. The world is full of motion and motion happens because of force. On this episode of Science Trek: The Web Show, ...

Newton's laws of motion, often perceived as abstract, are actually evident in everyday experiences. The first law explains inertia, demonstrated by seatbelts in cars. The second law, F=ma, clarifies ...

I saw it again. This time it was an introduction to an interesting online look at introductory physics. I was excited---but then, I wasn't so excited. Right there in the first video they talked about ...

During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes. In the old physics, mass and energy were separately conserved; particles’ ...

Researchers have developed a concise approach to understanding the mechanics of human running. The research has immediate application for running performance, injury prevention, rehab and the ...

Nudge something away from where it was at rest, and often it will push back. And then overshoot. From atoms to bridges to wheeled luggage, much of the world is in simple harmonic motion Yesterday my ...
