Friction - Lab musical theme ExampleA proof of an increase or decrease in galvanic pile of the normalitys examine is determined by the exponent and acceleration achieved from the essay. GoalsThe goal of the experiment is to verify the existence of Newtons second law by finding the coefficient of static friction, s and the coefficient of kinetic friction, k. using the experiment stated below.IntroductionHave you wondered the make-ups of mechanics? Well Newtons second law breaks it vanquish into simple understandable terms by providing a means of translating directly between the acceleration and labour acting towards a give mass or object. Theoretical background The experiments are based on the concepts of force and Newtons Laws of Motion, particularly Newtons Second Law which states that the acceleration of a body is directly proportionate 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 employ 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 let in acceleration of the sled, velocities of the sled at each photo-gate, net force acting on the string, and the time interpreted 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 employ 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 visual aspect the force, m used to show the mass being used and a used to show the acceleration of the object. The variables used by Newtons lay emphasis on the net force used exerted on the exp eriment 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 uninterrupted 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 appease 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 lamentable 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 an d inversely proportional to the mass of the body. This law is summarized by the formula F=ma which is verified quantitatively in this experiment. become 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 prudence dx. W = Fx ?x = F?xcos? Where ? is the angle between the direction of displacement and the direction of force. This relationship burn down be written in the vector dot product form W = Fx The
