NEWTON'S SECOND LAW OF MOTION
Abstract:
Newton's Second Law of Motion can be
summarized as
∑
F
=
m
a
. Where ∑
F
equals the net external forces, m equals
the mass under the influence of ∑
F
, and
a
equals
the acceleration of that object. This
equation can be confirmed through
recording the acceleration of a cart moved
via the tension force of a line pulled by
weights under free fall. The acceleration
found in this experiment can be compared
to the expected value of G = 9.81 m/s

OBJECTIVE
To confirm Newton's Second Law of Motion by measuring the
acceleartion of G.
II
PROCEDURE
The mass of the cart (M) and the Shook hanger were measured.
Graphical Analysis was prepared to record the mass of the weights used
(m), slope 1(
m
1
, m/s
2
), slope 2(
m
2
, m/s
2
), a
ave
(m/s
2
), and g (m/s
2
). The first
three are manual columns that were inputted as the experiment
proceeded while the a
ave
and g are calculated columns from the other
