Ultimately you get a differential equation which you can solve with a bit of code I wrote for you.
While you could technically cook a chicken by slapping it, as proposed by a recent meme, you might also cook your hand. We crunch the numbers.
Good ol’ trig: that bastion of angles and triangles is essential to calculating velocity, momentum, and much more.
Using footage shot by The Slow Mo Guys, you can get a pretty good estimate of the speed at which cracks travel through a sheet of glass.
The old-school way to navigate is with a clock and a sextant, but you can also hack together this alternative.
A warp-speed history of our quest for cheap energy, from prehistoric hunters to climate change.
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.
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.
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.
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.
New flying robots can pull loads that appear far too heavy for their tiny size. Here’s the physics of how they cheat friction with their tiny claws and gecko-like grippers.
Glow sticks and retroreflectors can help your kids be seen on Halloween night. Here’s how they work.
There’s more to it than just optimizing gas mileage. Our calculator will help you figure out the most cost-effective driving speed, personalized to your commute, wages, and fuel price.
These are the three key things that any person should know about the nature of science.
Estimating answers to everyday physics problems is an art form. Here’s one tip: learn to ignore what you don’t know.
In a collision, a car’s airbag has a tiny fraction of a second in which to inflate—which is why airbags use explosives.
Chewbacca is falling out of a moving train! Han rushes to save him! Turns out, ordinary physics would have saved him, too.
