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"

Force x distance is also torque if i remember correctly
