what are some good answers you've gotten?

Nothing quite so obvious as those. I was amazed at some people's lack of a concept of 'order of magnitude' in engineering. For example, I was in a class on materials engineering taught for mechanical engineers, and there was a question on failure time of an airplane wing under a given stress. One answer was something like 30x the known age of the universe! Just the lack of thinking 'hey, does my answer make sense?' was often apparent.

Yeah, the lack of common sense error checking always astounds me.

The one I see all the time are probabilities that are not between 0 and 1.

(Also, negative variance)

Yes, I teach probability and statistics
 
My maths teacher used to have a job checking papers for things that could make students do stupid things, he gave 'find x - here it is' as an example. Also he told us that answers to 'name this shape', with a picture of a shape included 'James, Alex and Richard'
 
Speaking of physics, i remember one test where we were supposed to find out how many meters an object traveled...

Well, i had NO clue, so I wrote down, "My pastor told me that Jesus is the answer to everything, so my answer is 'Jesus meters' "

He didn't think it was funny
 
We had a test in RE once, one question was a picture of the last supper and it said name 3 of the people at the table, now, I didn't care about RE so I wrote, Buddah, Hitler and David Beckham.

I had to do extra RE for a week. ****.

I would have said "The Father, The Son and The Holy Ghost" and see what he would have said. Jesus is technically all 3, isn't he? :p ;)
 
great answers, i wish i had come up with them! :D

for specialist maths last year, i had a question dealing with arithmetic sequences. It was asking how much shampoo would be left if she used 8mL, 4mL, 2mL... etc. for infinite washes.
My response was a drawing of a shampoo bottle, and i stated that after infinite washes, there would be no shampoo left.
 
Once back in high school I was bored in a study hall and the teacher asked me to type up the physics test for the freshman. After 3 or 4 questions and sets of answers on a multiple choice test I got bored. So I started editorializing in answers and adding additional ones.

This was at Montgomery Blair HS back in 89 or 90...

One teacher who used the test was amused.
The other had me re-edit it.

I thought God was the Father, Jesus was the Son, and the Onion dip was the holy Ghost.

But I'm not sure. Just seems to make more sense.
 
Some of these questions are badly written.

Very confusing use of the phrase 'comes to rest'. And where did this teacher learn to start a new line with a comma?

It's its not ' it's initial trajectory '. This schoolteacher needs a bit of remedial school. A bit of mis-spelling in internet posts doesn't bother me, but it should be right in exam papers.

This student can spell 'aesthetically' but not 'straight'? Hmm.

yeah - how can an object continue to move if it has come to rest? :rolleyes:
 
i had a couple of quizes where i answered some questions with that type of response. i always made sure i did well on the exams. in grad school i was helping out a professor by teaching one of his sophmore level classes, he was sick a lot that semester. it was pretty fun, but the students were not that bright. some of the answers they gave were pretty funny. my roommate and i would laugh our asses off reading some of them at the time. pretty funny stuff. i miss the carefree days of highschool and college.

You do realize that a projectile object is at rest (with respect to the ground) at the apex of its curve, right? Likewise, at the maximum compression, in between pushing into the spring and rebounding, there is an instant at which the block's velocity would be precisely zero. At this point the block's potential energy would be lost entirely to the spring.
 
What a great thread! Thanks for the laugh.

I don't have a picture, but a professor once asked the question "What is courage?" as an essay question on his final exam. A student simply responded "This is."

I heard the same, but with 'what is the hardest thing you ever did?'

ok, i see your point - i didn't consider a moment of zero velocity being 'at rest' in the strictest sense, but then Newtonian laws certainly aren't my strong point. :)
