1. Data for total mass changes, net force constant:

Mass difference:m₂- m₁=_ _ _ _ _ kg Net force:F_net = (m₂- m₁)g=_ _ _ _ _ N

m1(g)	m2 (g)	am (m/s2) measured
50	60	13.36
70	80	10.27
90	100	17.65
110	120	13.20
130	140	28.00

B) Calculate the total mass and the acceleration (use g=9.8 m/s²):

m1(kg)	m2 (kg)	mT (kg)	ac (m/s2) calculated	am (m/s2) measured	% error (amvs. ac)
0.05	0.06	0.11
0.07	0.08	0.15
0.09	0.10	0.19
0.11	0.12	0.23
0.13	0.14	0.27

B) In Excel, Plot a_m (y axis)vs1/m_T(x axis). Your graph should be scatter plots without line that connect the data points. Include the trendline and the trendline equation

Follow the rules for your plot:

Your graph should fill up a whole page, start your X and Y axis closer to the data points to eliminate the empty space in your graph. Edit the best fit line (trend line) equation to change Y and X to what you plot on Y and X axis, to match your plot.

D)What is the physical meaning of the slope? Discuss.

Slope=_ _ _ _ _ _ _ _ _ (Do not forget the units)

E)Calculate the % error between measured and calculated value.
