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 ...

A recent astronomical discovery has left scientists puzzled as they track an object accelerating in a manner that defies the current understanding of physics. This enigmatic object, potentially ...

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, ...

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 ...
