Space junk and meteoroids are falling to Earth every year, posing a growing risk as they re-enter the atmosphere at high speeds. Researchers are using infrasound sensors to track these objects, ...

If you drop an object, it will fall. It's a motion that we’ve all seen hundreds of times. We’ve also all seen plenty of the moon, which makes one complete orbit around our planet every 27.3 days (as ...

We know “what goes up must come down.” But WHY? "Drop" in to find out! We know “what goes up must come down.” But WHY? Drop in to learn about the gravitational forces like acceleration and air ...

We all know the importance of protecting an employee working at heights; we routinely use PPE such as full body harnesses, self-retracting lifelines (SRLs) and lanyards for fall protection to prevent ...

Like most real-world problems, physics can get very complicated. When a physicist considers the fate of this falling cockroach, their first step is to change the problem into something simpler. It's ...

Our motion perception is remarkably well tuned to detect small changes in speed and direction. For example, soccer goalkeepers need to precisely judge the speed, direction, and curvature of an ...
