Graph 1 and 2 are illustration
of the use of the polygon method in which you will measure the distance of the
starting point which is (0,0) to the end point which the last arrow will point.
And determine the angle using your protractor. As seen in Graph 1 and 2 , the gray
arrow represents the missing vector in which balances the rings which makes it
rest at the center of the table. In Table 2 , the percent error computed from
it’s R has a greater difference in value than the component method which provides
as proof that graphical method may not be as accurate at it seems.
Answers to Questions
is it important for the ring to be at the center? Since the mass hangers have
equal masses, can you disregard them in the experiment? Why?
It is important to keep the center to the
circle since the computation would be far off and the percent error may be
greatly affected since keeping balance means there’s no hanger gaining more
force than it already has.
a pull is applied on the ring and then released, why does it sometimes fail to
return to the center?
Since organizing the materials are not
perfect, outside it might look fine but pulling and releasing the ring confirms
whether it is in it’s correct positions.
is the significance of the resultant of to the remaining force .What
generalization can you make regarding their relationships?
Finding the resultant of the three means
the value must be close to . If the ring is in the circle it means, it’s
respected angles are keeping it balance and have specific distances from each
other. If the resultant is close to the value and the
process of computation was correct.
the order of adding vectors is changed (i.e. from )
will the resultant be different? Why?
Vector addition uses the rule of
commutativity which the result will be the same even if the process of addition
method of determining the resultant is more a) efficient b) accurate c)
practical or convenient to use? Defend you answer.
I believe the component method is more accurate since
does not require tools that would affect any sort of human error since in
graphical method requires the use of tools which may lead the cause of error in
the process of computation.
In physics, Physical
quantities use the quantities of scalar or vector. Which the difference of the
two is that scalar only contains magnitude which is something you are able to
measure, and vector quantity is the use of magnitude and direction where proved
that the balanced resultant is called the equilibrant. The reason why the ring
must be at rest at the center since sum of the forces put onto the ring makes
I believe that our
group was able to attain the right values that were required to perform the
task. As such as using the trial and error method which proved to be difficult
if the requirements were not meet since you’d have to repeat the process until
you finally have the correct one. Using the analytical method was far more
accurate and simple rather than to use tools to gather data.
be patient when gathering data since your attitude could affect how well you
are to put up with how many time you might have to re do the trials. Learning
how to follow the procedure.
