Question

determine the spring constant of a spring and to test the validity of Hooke's law. What are the uncertainties? Create an applied force vs stretch graph verifies discount the validity of Hooke's law. What is the slope?

mass kg	tension length cm	equilibrium cm	displacement cm	weight cm
0.040	4.35	4.03	0.32	0.392
0.150	7.95	4.03	3.92	1.42
0.100	6.30	4.03	2.27	0.98
0.200	9.70	4.03	5.67	1.96
0.300	13.30	4.03	9.27	2.94
0.500	20.20	4.03	16.17	4.90

Answer 1

From the graph we get, value of k as slope.

as we know, straight line equation is given by, y=mx+c if we compare it with f=kx

then slope gives value of k.

Uncertainities we get may be due to air resistance or instrumrntal error.
