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.

Density is mass of a unit volume of a material substance, expressed as kilograms per cubic meter in MKS or SI units. Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density, while the volume is equal to the mass divided by the density. The weight of a body, which is usually of more practical interest than its mass, can be obtained by multiplying the mass by the acceleration of gravity. Tables that list the weight per unit volume of substances are also available; this quantity has various titles, such as weight density, specific weight, or unit weight. D = mass/volume
You need to hang enough mass to the end of the spring to get a
4) The mass will be the first variable we manipulate. We will use the three smaller marbles of the four provided marbles. Do two trials for each marble and stop the stopwatch when the marble hits the spring. This will give us the time to calculate speed later.
Increments of five minutes were used for measuring the creatures. By the end of the experiment, the creature in Sprite had grown to double in length. The creature grown in water also doubled exactly in length. However, while the lengths were the same, creature two gained much more mass than creature one. Creature one grew from one point zero five grams to four point seventy-four grams. In comparison, creature two started the same as creature one, and grew to five point six grams.
Violence against women is a gender based violence because it is targeted specifically to women just for the fact that they are a woman, this can be due to many reasons like the attacker feeling empowered because they think of women as being the weak gender. The United Nations advocates against violence towards women in their Declaration on the Elimination of Violence against Women. They annotate that violence against women is a “manifestation of historically unequal power relations between men and women” It is something that happens more often that many people realize. Many times this type of violence happens behind close doors and goes to the extremes that many of the victims would not speak
In Silent Spring, Rachel Carson seeks to persuade the readers to open their eyes to a serious problem: the careless spraying of poison. Her purpose in writing the book is to protect plants, animals, and humans from poisons that never had to be sprayed. Carson uses invective, the ad hominem argument, and punctuation to attack the people responsible for the sprayings and yield an emotional reaction from the reader. Through the use of those strategies, her argument becomes stronger and more effective at revealing the horrors of species control.
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.
In analyzing the force associated with a certain spring, whether it is in you pen or under your truck, Hooke’s Law applies.
F = ma : where F is force; m is the mass of the body; and a is the acceleration due to that particular force
find the rate I have to find the mass change in 1 hour, and I will
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely proportional to its mass. (F=ma)(Newman)
The size of this depends on the mass of the object and the size of the
The problem of small oscillations can be solved through the study of molecular vibrations which further, can be introduced by considering the elementary dynamical principles. The solution for the problem of small oscillations can be found out classically, as it is much easier to find its solution in classical mechanics than that in quantum mechanics. One of the most powerful tools to simplify the treatment of molecular vibrations is by use of symmetry coordinates. Symmetry coordinates are the linear combination of internal coordinates and will be discussed later in detail in this chapter.
