Hi all,
I'm a physics teacher at an australian high school, and some kids that I teach have give me some interesting data reguarding spring constants.
They made a contraption to project marbles as part of an analysis of projectile motion, and part of the contraption was a spring, used to apply a force to the marble.
Too late, they realized they would like to know the spring constant of the spring, and were unable to hang masses etc on it ( was in contraption) so decided to measure the force needed to make the spring compress a certain distance using a spring balance to pull the spring into a compressed state.
The data they collected showed a nigh perfect F proportional to x SQUARED relationship.
Could the 2nd spring (in the balance) have affected these results?
