Abstract
This scientific investigation presents how simple harmonic motion happens in pendulum. Old pendulum clocks are basic example for pendulum that shows period and oscillation with respect to time. By using different masses, thread or string and protractors for angle calibration, this experiment was done. Twenty (20) back and forth movement was recorded with respect to the time it reached 20 periods. Each trial for 3 cases has resulted to relatively near oscillation per period. It was observed that whatever instances done, either play with the angles and masses for each trial, no abrupt or tremendous change was observed. Deviations for almost all cases were little to no value, nonetheless, …show more content…

T = 2π√(L/g)), where T is the period of the pendulum, L is its length and g is the acceleration of gravity.[1]
Many things in nature wiggle in a periodic fashion through vibration. One such example is a simple pendulum. A simple pendulum may be described ideally as a point mass suspended by a massless string from some point about which it is allowed to swing back and forth in a place. When the mass is displaced a small angle from equilibrium and then released, the pendulum undergoes simple harmonic motion. Theoretically, the period of a pendulum is independent of its mass, and depends on length according to the power-law relationship
Tα√L
where T is the period of oscillation and L is the length. This result can be determined using a dimensional-analysis approach. The independence of mass is a result of the fact that all objects are accelerated towards the center of the earth with the same acceleration of

    For each test, I was required to calculate the height of the pendulum required in order for it to have the same mass, or the quantity of matter affected by the external force of gravity, as my project. To find the height, it required understanding the process of the pendulum hitting my project step by step. As the pendulum is pulled back, it has its maximum potential energy, which is the energy possessed by a body by virtue of its position relative to other objects. When the pendulum is let go, it loses potential energy while gaining kinetic energy, or the energy that a body possesses by virtue of being in motion. At the bottom of the swing, kinetic energy of pendulum is the greatest because the change in potential energy equals the kinetic energy at the bottom of the swing. As the pendulum hits my project, there is an impulse, a force acting briefly on a body and producing a finite change of momentum, between the pendulum and project. As the pendulum hits my project, the project carries the momentum of the pendulum with it. By working in reverse order, the height of the pendulum required was

    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

    The first record of the movement of the planets was produced by Nicolaus Copernicus. He proposed that the earth was the center of everything, which the term is called geocentric. Kepler challenged the theory that the sun was the center of the earth and proposed that the sun was the center of everything; this term is referred to as heliocentric. Kepler’s heliocentric theory was accepted by most people and is accepted in today’s society. One of Kepler’s friends was a famous person named Galileo. Galileo is known for improving the design and the magnification of the telescope. With improvement of the telescope Galileo could describe the craters of the moon and the moons of Jupiter. Galileo also created the number for acceleration of all free falling objects as 9.8 meters per second. Galileo’s and Kepler’s theories were not approved by all people. Their theories contradicted verses in the bible, so the protestant church was extremely skeptical of both Galileo and Kepler’s

    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.

    Although the group tried its best to get accurate data some problems that could have affected the data would have been that we used 2 timers, and we would pick the better time out of the 2. So that could have affected the reliability/accuracy of the groups data. On one of our samples(of data) was at angle of 45 degrees and the group tested it out 3 times at that angle giving us, 1.45sec, 1.56sec, and 1.35sec. Now you as the reader can see that in general this is relatively very close to a 1.5 period. So in the group's general consensus we had completed our mission of getting a 1.5 period. Little did the group know but along the way of graphing the average of all times for all the different ball elements (cork&steel) it was discovered that at no matter what angle less than 45 degrees the pendulum would always be at a 1.5 second period. The graph proved this because when all points where connected it was a straight line which means it was constant. Therefore the group came to the conclusion that no matter what variable you change, whether it be the measure of the angle, the string length(holding the ball), or even the element/mass of the ball, it did not matter because you would always get a 1.5 second

    The gravitational force at the surface of the planet is the force that binds all bodies to earth, this force is one of the four forces recognized by physicists, and this kind of force is known as "gravity" it attracts every celestial object to earth, and though it is the most important of the forces essential for our lives, it is the least comprehended of them all Throughout ages scientists have tried to solve the mystery of gravity, and one of the first discoveries concerning gravity was made by Aristotle who concluded from his experiments that the downward movement of any body is that has weight had a proportional relationship between its quickness in motion and its size. However this theory was accepted for centuries, but after a series of experiments made by Galileo, Aristotle's theory was proved to be incorrect, as Galileo said after a series of experimenting at the Pisa tower that bodies of different sizes fall with the same speed. Later on, the idea that the force is needed so as to change the motion of the body was discovered. After that a great scientist was to improve all the previously accepted theories, this scientist was Newton who was to make decisive advances in understanding gravity. In his first law Newton said that a body in state of rest or uniform motion in a straight line will keep on moving unless acted upon by a force, while in his second Newton expressed his first law in a more quantitative way as he said that force acting on a body is the rate of change of it's momentum which can be put in a rule as F= ma Where (F) is the force acting on the body while (a) and (m) are the acceleration and inertial mass of the body respectively. Newton also made the law of gravitation in which he expressed the gravitational force of attraction between any two bodies acting along the line joining them as Where (m) is the mass of the two bodies and (r) is the distance between them, while (G) is the proportionality constant known as the constant of gravitation, afterwards Newton made his very important assumption in which he showed that the inertial mass of a body is identical to its gravitational mass which implied that the gravitational force exerted on or by an object is directly proportional to its inertia.

    When a molecule vibrates, the atoms get displaced from their respective equilibrium positions. Consider a set of generalized co-ordinates q_1,q_2,q_3……… q_n (the displacements of the N atoms from their equilibrium positions) in order to formulate the theory of small vibration. As these generalized coordinates do not involve the time explicitly, so classically, kinetic energy (T) is given by
