THE ANALYSIS QUESTIO
NS
IN YOUR LAB
NOTEBOOK USING COMPL
ETE SENTENCES.
1.
Did your predicted graph match your results?
Explain how
your predicted graph for Force vs
Acceleration did or did not match your results.
2.
Are the net force on an object and the acceleration of the
object directly propor
tional?
Explain
using lab data

.
3.
What are the units of the slope of the force
vs.
acceleration graph? Simplify the units of the
slope t
o fundamental units (m, kg, s).
(Hint: 1 N = 1 kg
m/s

)
What does the slope of the
graph experimentally provide?
What general equation is
created by finding the slope of the
graph?
What Law is ‘written’?
4.
How could you modify the lab to further identify the
relationships between the three terms?
Identify a
ny tools, materials or methods which could be used to further
refine the experiment
and explain how you would apply them to the experiment.
