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 ...

Gravity is a fundamental force of nature; it is an attractive force between any objects that have mass. The strength of gravity between everyday objects, such as a desk and a chair, is extremely small ...

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 ...

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 ...

Gravity, in the literal sense, keeps everyone (and everything) on Earth grounded. It acts as the anchor that prevents objects ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

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 ...

Gravity has suddenly become a hot topic in science. In the past few years, gravitational waves have been detected for the first time: ripples in the fabric of space, coming from colliding black holes ...

Neil deGrasse Tyson explains how gravity truly acts on falling objects, revealing the physics behind motion, acceleration, and why our everyday experience often hides the universe’s deeper rules. Ford ...
