Newton's Second Law

northwards Second Law and the discipline-Kinetic Energy Theorem October 13, 2010 airlift This prove utilizes an air track first as an given over shroud with the slider accelerating repayable to gravity and entropy as a level surface with the slider accelerating due to the coerce of an attach free-falling goal of known mass. In both cases, the Work performed is compute based on formulas for mechanical lop and for kinetic energy. The devil results are compared. The first part yielded an average speedup of 0.715 m/s2 (a 1.58% error) and the average result for the Work performed was 0.0204 N*m with precisely a 0.9% difference. The second part suffered critical errors due to unconventional data and the results are not significant or useful. atomic number 7s Second Law and the Work-Kinetic Energy Theorem description of Experiment The purposes of this prove are to measure the acceleration of a glider on an air track acted on by an unbalance throw and compare this to the value predicted by Newtons second faithfulness and to compare the amount of work performed on the glider to its change in kinetic energy. The opening behind the experiment is based on Newtons second law that states an accelerating (a) object experiences a net soldiery (F) that is directly relative to its mass (m).

F = m * a If that force causes an objects displacement (d), then by definition a genuine amount of work (W) has been performed. For communicate in one symmetry on an inclined piece of paper the expressions reduces with ? being the angle of the incline. W = F * d W = F * cos ? * d Additionally, the energy (K) a! ssociated with an objects velocity (v) is defined as: K = ½ m * v2 By starting with Newtons second law and utilise the definitions of work and kinetic energy it can be shown that the do work done on an object pass on equal the change in kinetic energy of that object. W = ?K Utilizing trigonometry, the equation W = ((m*g*h)/L)*d is apply where (g) is the acceleration due to gravity (9.81...If you want to get a spacious essay, order it on our website: OrderCustomPaper.com
