Which ones were incorrect?:wah:

tee hee :wah: i have a friend who marks maths exam papers and after one particularly difficult question,someone had apparently drawn a tube of smarties and written only smarties have the answer:p

You should have heard me laugh at the elephant one.

:wah: :wah:

From the elephant one:- "Does the object continue to move after it comes to rest?"

Even funnier than answer so it is.

A wee question for the person who devised that question - How can an object continue to move after it has come to rest?

:wah: those were funny!

The question ought to make clear its assumption that the spring's 100% efficient at storing and releasing the energy though.

Continue to move = moving AKA not at rest

at rest = not moving.



I wasn't questioning the physics, merely the use of language.

I had a math teacher in college who would grade based on creativity. If I were the teacher grading the "find X" paper that student would have received credit for their answer. I have never had to find "X" in my adult life, but I have had to be creative and fast on my feet.

The plus side of grading exams, Pinky! You will laugh through them-and think of summer vacation!:-6

It's a simple description of a moment at which every component in the system has a velocity of zero. Honestly, nothing's moving at all when the spring's as tensed as it will get.

Pinky, those were quite funny. I bet you had a good laugh..
