Write your guess using the form 'if .... then ....'
B) Open the file HookLaw2.ggb and varied mass of small weights hanging from the spring to verify or refute the assumptions That you have written in A). You modify your previous guesses? If so, why? If not, giustificatele.
C) How to change the differences between the y coordinate values of points on the graph if you change the mass of small weights? Because? Your guess is always true? Can you prove it?
D) There is a formula that expresses the elongation of the spring to vary the mass? Justify your answers.
E) Is it possible to express with the formulas varies as the length of the spring to vary the hanging mass? Justify your answers.
