| CONCLUSIONS
Through our observations, we have shown that Newton's laws can be
applied to the game of pool. First, the collisions between the balls
are elastic, and therefore momentum is conserved within the system.
This was studied through the tracking of their motions to find momentums
before and after the collisions. We used the general equation Ptotal = (m1v1) + (m2v2)
+ (mnvn), to find each initial and final momentum.
Since the initial and final values were statistically similar, with
some variance, we were able to conclude that momentum was conserved
for each elastic collision.
Conservation of momentum prompted the study of angles of deflection.
Through the tracking of ball momentum and the angles between the
balls after collisions, momentum is conserved yet again. One sedentary
ball was hit by another ball with an initial momentum. The resulting
vectors of momentum were 90 degrees apart because they add up to
the initial momentum.
We studied the center of mass by colliding three balls and found
that it moves at a constant velocity. This was accomplished by tracking
the position of the three balls with respect to time and using the
equation; . This equation yielded the position of the center of mass
with respect to time. When these points were graphed, the center
of mass had a linear relationship, thus having a constant velocity.
