Part 1. Total mass constant

1. Data for total mass constant, net force changes :Total mass:m_T = m₁+ m₂=_ _ _ _ _ _ _ kg, a_mis the uncertainty

m1(g)	m2(g)	am (m/s2) measured	am (m/s2) measured
95	105	26.5	0.01
90	110	16.74	0.001
85	115	16.41	0.001
80	120	20.46	0.001
75	125	11.79	0.001

B) Net force and acceleration calculations Table (use g=9.81 m/s²):

m1(kg)	m2 (kg)	m2-m1 (kg)	Fnet (N)	ac (m/s2) calculated
0.095	0.105	0.01	0.098	10.204
0.090	0.110	0.02	0.196	5.102
0.085	0.115	0.03	0.294	3.401
0.080	0.120	0.04	0.392	2.551
0.075	0.125	0.05	0.49	2.040

C) In Excel, Plot F_net(y axis)vs. a_m (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.

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

D) What does the slope represent? Explain and calculate a percentage error.

E) What is the value of the intercept (where best line intersects Y-axis). How is this related to friction force?

Intercept=Friction force=_ _ _ _ _ _ (N)
