Newton's Second Law

northwards Second Law and the operate-Kinetic Energy Theorem October 13, 2010 plagiarize This prove utilizes an air track first as an given over shroud with the slider accelerating ascribable to gravity and entropy as a level surface with the slider accelerating due to the hook of an attach free-falling goal of known mass. In both cases, the Work performed is compute based on formulas for mechanical escape and for energizing energy. The devil results are compared. The first part yielded an average acceleration 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. due norths Second Law and the Work-Kinetic Energy Theorem rendering 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 theory behind the experiment is based on Newtons second law that states an accelerating (a) object experiences a net oblige (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 movement in one symmetry on an inclined carpenters plane the expressions reduces with ? being the angle of the incline. W = F * d W = F * cos ? * d Addit ionally, the energy (K) associated with an o! bjects velocity (v) is defined as: K = ½ m * v2 By starting with Newtons second law and employ the definitions of work and kinetic energy it can be shown that the come in 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 utilize 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
