Investigating How One Factor Affects the Period Time a Mass on the End of a Spring Takes to Complete One Oscillation
Planning
Variables
=========
The aim of these experiments will be to see how one factor affects the
period of time a mass on the end of a spring takes to complete one
whole oscillation. One whole oscillation means the mass returning to
its original position, be it the equilibrium or not.
I will look at the independent variables (variables which are not
caused as a result of another variable). The dependent variable in
this case is time
* Mass - the size of mass on the end of the spring. Bigger mass may
affect the time it takes
* Length of spring - if the spring is longer, the mass would have
further to travel and this will affect the time it takes to
oscillate.
* Tension of spring - the more tension in the spring may result in
the mass oscillating faster as there would be more tension. This
would prevent the mass pulling the spring too far and thus mean
the oscillating time would be shorter.
* Gravity - the force of gravity would affect the mass, as if the
gravity was less the mass would take longer to pull the spring
down. If the gravity were stronger, the mass would take longer to
go back to the equilibrium.
* Temperature - if the temperature changed, the spring would be more
ductile and this could mean the spring would deform earlier than
it would at room temperature.
I have chosen to make mass the variable, as this is the easiest
variable to use in this experiment.

The goal of this experiment is to develop a theory, which allows us to understand the motion of a marble.
The spring symbolizes the beginning of different results blossoming under the unchained sun. In contradiction, the spring symbolizes the budding of something seeming so beautiful but raiding with poison. This bud is a mere seedling of hope that is planted in their hearts, maybe awaiting to be dried upon by the sun’s rays or perhaps to be drowns by pellets of rain
One of the sciences in this project is potential energy. Potential energy is the energy something has based on somethings shape or position. For example, if someone holds a ball up in the air the ball has potential energy. If someone stretches or twists a rubber band thr rubber band also gains potential energy.

If an object of mass 'm' moves at speed 'v'. Then we can say it has a
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.
Results: The experiments required the starting, ending, and total times of each run number. To keep the units for time similar, seconds were used. An example of how to convert minutes to seconds is: 2 "minutes" x "60 seconds" /"1 minute" ="120" "seconds" (+ number of seconds past the minute mark)

The size of this depends on the mass of the object and the size of the
Dependent Variable ------------------ Rate at which the bubbles of oxygen rise, which will be calculated by observing how many bubbles of oxygen rise to the surface of a measuring cylinder (by means of downward displacement) in one minute. This will be measured in bubbles per ten seconds. Control variables: ¨ Volume of substrate used: 100ml ¨ Temperature: taken place at room temperature 21 degrees centigrade ¨ Type of substrate used: Hydrogen peroxide ¨ Mass of meat used: 5g ¨ Amount of water in the test tube in which the oxygen bubbles downward displaces in the water. This is so the time taken for each individual bubble to effectively rise to the bottom of the test tube will take the same amount of time.

The second law is, “the relationship between an objects mass (m), its acceleration (a), and the applied force (f) is F= ma.” The heavier object requires more force to move an object, the same distance as light object. The equation gives us an exact relationship between Force, mass, and acceleration.
