Investigating the Oscillations of a Mass on a Spring
Aim:
In this physics coursework, I'm here to investigate the oscillations
of a mass of a spring. In this investigation, the oscillation means
the wave moving with periodic regularity. In this investigation, I can
use any mass and many springs, so that I can investigate the
oscillations.
Variables:
I believe there are many factors or variables, which can affect the
time for 1 oscillation. These can be:
· Mass of weight - I believe it will have a very big impact on the
time for oscillations.
· Number of springs - The number of springs will affect the affect the
time for oscillations a lot just like the number of mass, because of
the strength of the springs, and this depends on the number of
springs. The number of springs can affect the strength of springs and
this depends on the arrangement of the springs, which will be shown
much more detailed below.
· Arrangement of springs - First of all, there are 2 ways to arrange
the springs, and they are: Series or Parallel. Springs in series
extend further than springs in parallel. Also, during the trial
experiment I discovered that springs in parallel do not extend in a
straight line, they move from side to side and the springs can be
tangled up and this could be a major problem. Therefore, this would
affect the time taken to complete the given number of oscillations.
So, I will only do the springs in series, as the longer the extension,
the more accurate and complex the results will be. So, the arrangement
of springs will also affect the time taken to complete the given
number of oscillations. It can affect the spring constant, because
when the n number of springs of the same type is used in parallel, the
value of spring constant is n times larger than the spring constant of
one spring. When n springs of the same type are used in serial, the
m= 10km2 x 1000m x 1000m = 107m2 107m2 x 15= 1.5 x 1.8m3 = 1.5 x 1011kg
Input variables In this experiment there are two main factors that can affect the rate of the reaction. These key factors can change the rate of the reaction by either increasing it or decreasing it. These were considered and controlled so that they did not disrupt the success of the experiment. Temperature-
... while weighing the reactants would try and avoid letting the reagents get in contact with apparatus that may not be necessary so as to avoid loss of some the substance and this way the exact mass would be achieved.

In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.

Death and terror, the inevitable of demise of everything and everyone, there is no escape. It bugs us everyday to know your going to die, but you just don’t know when, just like the pendulum hangs over the main character in the story.
The size of this depends on the mass of the object and the size of the
The time taken for this to happen is the measure of the rate of reaction. We must do this several times, and change the concentration of sodium thiosulphate. The rate of reaction is a measure of the change, which happens during a reaction in a single unit of time. The things that affect the rate of reaction are as follows. Surface area of the reactants Concentration of the reactants
