Goals:
The goal of the experiment is to verify the existence of Newton’s second law by finding the coefficient of static friction, µs and the coefficient of kinetic friction, µk. using the experiment stated below.
Introduction:
Have you wondered the make-ups of mechanics? Well Newton’s second law breaks it down into simple understandable terms by providing a means of translating directly between the acceleration and force acting towards a given mass or object.
Theoretical background:
The experiments are based on the concepts of force and Newton’s Laws of Motion, particularly Newton’s Second Law which states that: the acceleration of a body is directly proportional to the net force acting on the body, and inversely proportional to the mass of the body. From this definition, the equation Net Force = Mass x Acceleration (Fnet = mass x acceleration) is derived. Air tracks were used to reduce friction; the little amount of friction that remains in the system is negligible in the data. The suspended mass was subject to gravity which has a constant acceleration of -9.81 m/s2. The variables were solved to include: acceleration of the sled, velocities of the sled at each photo-gate, net force acting on the string, and the time taken from release to the first photo-gate and between the photo-gates. Acceleration was calculated using the formula: Acceleration= Velocity/ Time. The experiment is commonly used in mechanics fields to determine the acceleration acting towards a given mass or object.

Theory: The variables to be used in the experiment and their explanation involves F used to show the force, m used to show the mass being used and a used to show the acceleration of the object. The variables used by Newton’s lay emphasis on the net force used exerted on the experiment in question. The relationship between force and motion was initially discussed by Aristotle (384-332B.C). He proposed that the natural state of an object was during rest, and force was required to put an object into motion, therefore, a continuous force was necessary to keep the body in motion. Galileo Galilei (1564-1642) argued that a body at rest is a unique case of a more broad case of constant motion. He noted that in the absence of friction acting on a body to slow it down, the body might continue to move in a straight line forever. He proposed that bodies remain at rest or in a state of constant motion unless an external force acts on them to change this motion. Frictional force is a force unlike other forces which accelerate or slows down a moving body (Lerner & Lawrence, page 51). Isaac Newton (1642-1727) sanctified the relationship between force and motion by proposing that the acceleration of a body is directly proportional to the net force acting on it and inversely proportional to the mass of the body. This law is summarized by the formula F=ma which is verified quantitatively in this experiment. Work done i.e. physical work defined in terms of physical quantities is expressed as a product of positional change multiplied by the component of force Fx in the displacement direction dx. W = Fx ?x = F?xcos? Where ? is the angle between the direction of displacement and the direction of force. This relationship can be written in the vector dot product form W = F??x The ...Download file to see next pagesRead More

Newton's Three Laws, Friction and Electrical Circutes
...unless someone kicks it or carries it. On the second case, consider a ball rolling with a constant velocity. Without friction and other forces including that of gravity, the ball will continue rolling with the same velocity unless it hits something or someone kicks it. Understanding the concept of a net external force is crucial in understanding Newton's first law. To illustrate this, consider a rope being used in a tug of war. There are two opposing forces in the activity but if the two sides pull with the same force then the rope would not move. That is, the two forces cancel each other out resulting to no net force on the rope. Thus, forces may be acting on an object but they are applied in such a manner that they...

As an anthropological work, Tsing illuminates her readers as to how connections are made globally that through a network and a chain of reaction the cultural values of the Indonesian rainforests are pulled into the limelight of the world. However, it isn't only a dimension of interconnectivity that prevails in Tsing's book but it also explores power dimensions (Neuman 2004:11). There is a power dimension within the global scope that wrests its control over the Indonesian environment, from multinational corporations vying for profit...

... A Fiction Essay: Fragments of a Dream The school yard was beautifully landscaped and daffodils, roses, jasmine and lilies on the small pond. There was the image of the Virgin Mary, almost five feet in height, with her hands clasped together in prayer, standing by the pond beyond any student’s reach. As one gazes on her feet, small colorful fishes are seen playfully exploring the shallow depth; it was all so real. We were playing around the pond which was located on a small hill. Seven steps need to be alighted to reach the top. Our quick, excited steps run one after the other, not minding the intense heat from noon rays of the sun. After a hurried lunch of rice and ham, I invited Victoria to play with me at the Grotto. She... A Fiction...

...Friction: Ethnography of Global Connection Kofi Anan says; “It has been said that arguing against globalization is like arguing against laws of gravity.” (Anan) Since the beginning of the 18th century the term globalization has taken its toll. We have seen it in all aspects whether its free trade or acknowledging cross border cultures globalization is on the rise. It is the continuous process of interchanging of ideas, world views, culture, and other aspects of life on international level. To understand the concept of globalization it is important to understand its basic ideas put forth by IMF; Capital and investment movement, Trade and transaction, Migration, and lastly Movement of people and or diffusion of...

...Friction by Tsing Introduction Arguably, the book by Tsing stresses that globalization is a system that unites the world into asingle imperial system. She further states cultural differences are a critical concept since this can lead to rearrangement of power and culture. Unequal encounter, heterogeneity, and diversity concept require careful handling. According to her friction helps in understanding universalism: freedom, prosperity, and knowledge (Tsing, pg29). She questions the ability of globalization in forging connection yet it posits that unity of purpose is unnecessary. Forging universal connection is facilitated through the flow of information. The flow of information is critical in engaging the...

...Lab 4: Friction Friction: Determination of µs and µk Interaction of two bodies on the surface always involves contact forces. Contact forces are grouped into two (normal and friction forces). The normal force is perpendicular to the contact force while a friction force is parallel to the contact surface. On the other hand, a friction force is a type of force that acts on a moving body and it is always parallel to the motion of the object. There are two types of friction called kinetic and static friction. A static friction force (fs) acts on an object at rest while kinetic friction (fk)...

Friction
...Friction Friction Theory: Friction is a force that always tries to limit the pull or push force when one object is makes contact with another surface. In more simple way, friction is the force that restricts the motion of the one object sliding at another object. Friction is also important in many matters, like cars and vehicles use the friction between tires and roads to move the vehicle. On the other hand, it produces wear and tear in the engine parts when they slide over one another. In order to estimate the friction proper mathematical systems are utilized to evaluate the force of friction between the...

Friction, Work, And Kinetic Energy
...INTRODUCTION Trying to slide any object leads to creation of an opposite force , that demands more force to be applied to the object for it to move hence more work is required. The opposite force that opposes the force being applied to the box is static friction. Application of a light horizontal push that does not move the box reduces the static friction force which is also directly opposite to the push. Pushing it harder increases the frictional force so as to match the magnitude of the push. There is a limit to the magnitude of static friction, that eventually makes it possible to apply a force larger than the maximum static force, making the box to start moving. ...
