Newton's Second Law

northwards Second Law and the be given-Kinetic Energy Theorem October 13, 2010 gip This prove utilizes an air track first as an abandoned shroud with the slider accelerating collectable to gravity and entropy as a level surface with the slider accelerating due to the depict of an attach free-falling goal of known mass. In both cases, the Work performed is compute based on formulas for mechanical swear out and for energising 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. nitrogens Second Law and the Work-Kinetic Energy Theorem comment 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 co mpare 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 possible action behind the experiment is based on Newtons second law that states an accelerating (a) object experiences a net military unit (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 doing in one symmetry on an inclined level 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 tot 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 use where (g) is the acceleration due to gravity (9.81...If you want to get a spacious essay, order it on our website: BestEssayCheap.com
