A couple of notes: In the diagram, I just drew a human with a flashlight instead of a car with headlights. (I'm sure we can all agree that it's basically the…

But it’s difficult to say for sure, since the NASA data is based on experimental evidence. And on top of that, every human is different, with different…

Let me give a real-world example. Once my class was working on the momentum principle, which gives a relationship between the net force on an object and that…

The important thing is that this is the equation of a parabola. Looking back at the vertical position data from the video, it at least seems fairly…

Yes, this is just an image—but it's really balanced. If you run the code, you can see that it is indeed stationary and doesn't tip over. It seems pretty…

Right now, you can probably just ask your smartphone to tell you the charge of a single electron—the fundamental unit of charge. (It has a magnitude of 1.6 x…

Gymnastics is an extremely difficult sport, and not just extreme for Olympic athletes like five-time (so far) medalist Simone Biles. The physics is also…

I’m a huge fan of both science and the Marvel Cinematic Universe, so it’s awesome when these two collide. That’s exactly what happened in Episode 5 of…

So, how do you make it happen? Simple: You use another magnet. Putting a strong magnet near those unaligned domains will force them to line up. It's actually…

Let's suppose you need to measure the mass of some water, and you want to construct a scale to do it. But you are in a normal house filled with normal stuff.…
