1. What physics quantity does the slope of the velocity
vs.
time graph represent?
2. What does the slope of the acceleration
vs.
applied force represent?
See step #13 in the manual.
3. What is the experimental value of the total mass of the system and it’s corresponding uncertainty?

4. Use the digital scale to measure the total mass of the system (cart, hanger, weights, and string).
This is the theoretical value of total mass,
m
0
. Calculate the percent discrepancy between
m
0
and
m
total
and show your work

using Eq. (6) in the manual.
6. Using the value of
a
avg
you just calculated along with the masses you determined with the digital
scale, show a sample calculation of gravitational acceleration using Eq. (7) in the manual.
7. Using the mean value of
g

Type Discussion below. It is a narrative that consists of 5 paragraphs: > Provide objectives of the experiment. > Explain theoretical concepts tested in this experiment. Describe the procedure of the experiment. > State the results. Provide numerical values with their units. Discuss the results, connect their values with the theoretical concept. > Discuss all possible sources of errors. > Conclude whether or not the results of your experiment verify the law you studied.
