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 ...

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 ...

It’s been demonstrated since the 1500s that, when falling toward a certain body, objects fall at the same rate. Everyone from Galileo in Pisa to David Scott on the moon demonstrated that. But what if ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...

This is a fantastic question, and the answer highlights some of the most counterintuitive aspects of the theory of general relativity. The short answer is no, but let’s delve deeper into a few of the ...

Newton's laws of motion predict that an object will fall when its centre-of-mass lies beyond its base of support. But how does your brain know whether the tower will fall or not? Scientists in Germany ...
