90%. Two of the questions were stated ambiguously (in one, the question treats acceleration as an unsigned quantity). Not bad, given that it's been 28 years since my college physics classes.

72.5 though one was a misreading (thought it said "millimeter" not "milliliter") and one i somehow checked the wrong box. and, i protest the "electrocution" question. it relies on the specific meaning of "electrocution" (always fatal) and not the common usage (any shock will do). not exactly a physics question.

I call subjective! "13) An astronaut orbits the Earth 500 miles above its surface. She appears to be weightless because there is virtually no gravitational force on her. X Your Answer: true" - She does appear to be weightless, where in fact she is not. 30) An atom is just like a tiny solar system in which the nucleus is like the Sun and electrons are like tiny planets orbiting the nucleus in elliptical paths. Your Answer: false - A tough call. What just "just like" mean. No two solar systems are even "just like" each other. I got this one correct, but don't like it. Oh yes, 67.5%.  Not too bad for mainly twenty year old school memories - all except the overly emphasized difference between vectors and scalars.

Many of the questions aren't very clear - though considering they can be answered "true" or "false" helps a bit. I didn't fail on these trick questions, though :cool:

And the household electrocution was because I pulled the Correctly Marked Fuse out of the Fusebox, unfortunately whilst it was a correctly marked fuse, it was in the Wrong slot.

Suddenly my paranoia with all things electrical is validated. I always check for a pd before touching anything, even if I was the one that flicked the trip/switch etc. Mr Paranoia has yet to be electrocuted, which is bloody amazing.

There are alot of them. I'd say this "Basic Physics Savvy Quiz" is more an exercise in how well you know the test writer so you know when they're using specific language and when they're not - e.g., more an exercise in how people interpret questions than an emphasis on the questions themselves. Some of the questions are hard to misinterpret. Other questions are designed to be. Nobody who was really trying to gauge your physics savvy would ask questions that way.

92.5% - But I'm embarrassed that I answered false to "Under typical conditions, ice melts and water freezes at the same temperature." :-O

82.5 and I got a D for DumbA** in college physics.

The part that's false is "there is virtually no gravitational force on her" - there is actually quite a bit of gravitational force on her, and if she wasn't moving in orbit, she would be falling to a fiery death. What we call "zero gravity" isn't really zero gravity.

I thing you mean you have been shocked several times - electrocution [^] is the fatal form of being shocked by electricity.

80% with a couple of guesses right. Some of the questions were iffy and could be interpreted in other ways. Fun though and thanks for sharing!

maybe your 'puter was electrocuted? :)

82.5% although I feel some questions were abgiuous. For example the one about the car's engine, what happens with a torque converter, turbo. Yes I'm being picky but most cars now-a-days have these so...

97.5. Was tricked by the one question I should have got: clouds are water droplets, not vapour! :doh: (I count that as samantic cheating in an exam and demand a recount!)

The average velocity of a car that goes around a circular track depends upon one's reference frame. If one uses an gravitational/inertial reference frame, a car which makes an integral number of circuits in an integral number of 23h56m intervals will average roughly zero velocity relative to any other apparently-non-moving point on the planet. Since the circuits were driven over a two-hour interval, however, a vector from almost any reference point to the spot on the track where the car began/ended the exercise will have changed direction quite considerably (up to 30 degrees).

I don't consider it semantic cheating, since the amount of N2 surrounding the water droplets is greater than the amount of water vapor there.
