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 doesn’t discriminate. An experiment in orbit has confirmed, with precision a hundred times greater than previous efforts, that everything falls the same way under the influence of gravity. The ...

If there's one thing that you should learn from physics, it's that big things are not like small things. I don't just mean that big things are bigger, or even that big things are more massive. (That's ...

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists have sought to ...

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. Home ...
