We did the math on a famous thought experiment by Isaac Newton involving a very tall mountain, a wicked fast cannonball, and good old gravity.

In the new 'Aquaman' trailer, the superhero bounds from the water and lands on a submarine. It's a fantastical leap grounded in serious physics.

NASA just plopped a lander on the surface of Mars. This simple game lets you see if you can do the same.

Using video of a football collision, you can figure out the velocity and momentum of the players involved.

In a scene from season one, Jim Holden shows exquisite command of high school physics as he maneuvers himself onto a spaceship gangway.

The buoyancy force gives you the boost that helps you float and do cool maneuvers in water. This experiment lets you see it in action.

We can use video analysis to test whether an escape pod carrying R2-D2 and C-3PO in the first Star Wars movie was modeled using a KFC bucket, as one theory claims.

Centuries-old ideas about force and motion have an intuitive appeal that is enduring but oh-so-incorrect, as these simple experiments show.

Take some simple measurements, add a dash of algebra, and you basically have a way to measure an unknown mass.

The probe just broke the record to become the fastest human-made object, relative to the sun. Here's what that record really means.
