how much would work increase?
I figured OK...F=kx....so if x increases by a factor of 4 then the F in FxD= work should increase by 4.
The answer key however says to use (1/2)kx^2 formula however ....but i thought that was equal to potential energy...not force. Anywho...it says the work increases by a factor of 16.
whats going on here???
