Great quiz! I would like to see "Index of Refraction" accepted for "Refractive Index", and I found the last one a bit misleading (although I was on the right track, thinking "Bernoulli's pressure") but not sure if it should stay or go. It looks like only 1% got it, so it might be on the "too difficult" side

Perhaps accept "Potential energy" for "Gravitational potential energy".

I realize it's not entirely correct, and I did get "Gravitational Potential Energy", but I think it could be nice to accept Potential Energy for that one, since a lot of people studying mechanics would probably think of it as just "potential energy" and perhaps not spell it out in detail.

Still, great quiz!

"Index of refraction" should really be accepted as well for "refractive index"

Nice quiz ! It has been quite a while. And seeing this out of context makes it harder, and it being in english even more so. My brain needed to shift into new gears ( and in this second day of the new year, it isnt quite up to speed yet haha)

I got three "wrong" despite trying "index of refraction," "potential energy," and "gravitational energy". I agree with other folks that those should be counted.
