    INTRODUCTION During collisions involving two bodies‚ equal and opposite forces are set up between them. These impact forces influence the subsequent motion of the bodies. Momentum of the system (consisting of both bodies) is preserved if both bodies are free to move in space. This is because there is no external forces act on the system. The forces acting between the bodies during the small interval of time when they are in contact cause changes in the velocities of each separate body. An

    Maggie Haas Reiter Honors Physic 8 March 2015 Background Information: Anything that has mass and is moving has momentum. Momentum is equal to the objects mass times its velocity. Momentum is conserved‚ which means that “momentum before an event equals momentum immediately after‚ or pi=pf”. Since pi=pf‚ then pai+ pbi = paf+ pbf and (ma* vai)+ (mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an object has a speed and direction. Using the formula “(ma * vai) + (mb * vbi)

    the principle of conservation of momentum in collisions using two bodies. We also calculated the amount of kinetic energy in elastic and inelastic collisions before and after the collision. Introduction: When bodies collide with each other‚ the total momentum p = mv‚ is always conserved regardless of the type of collision provided no external forces are present. There are two types of collisions. In an elastic collision‚ both the kinetic energy and the momentum are conserved. An inelastic collision

    STARWARD ACADEMY WORKSHEET # 2 MOMENTUM DUE: 1. Calculate the momentum of an object if: (a) its mass is 4.0 kg and its velocity is 8.0 ms-1 (b) its mass is 500 kg and its velocity is 3.0 kms-1 (c) a force of 20 N is applied to it for 6.0 s and it moves from rest (d) its mass is 2.0 kg and it falls from rest for 10 s (assuming g = 10 ms-1 or 10 Nkg-1). 2. A car of 1200 kg is pushed along a level road by two men. If they use a force of 800 N and frictional forces acting against

Market efficiency anomalies such as momentum‚ reversal effects‚ book-to-market effects and post-earnings-announcement drifts have contributed to the argument against the idea of market efficiency.

    1. What is a momentum investment strategy? Momentum is the phenomenon that stocks which have performed well in the past will continue to perform well in the future‚ and that stocks which have performed poorly will continue to perform poorly. Therefore a momentum investment strategy is to invest in short term portfolios that have high returns in the past‚ and to short those with low returns over the same period. 2. Analyze these portfolios. By analyzing monthly returns of all 10 portfolios from

The Gilded Age was a term made up by Mark Twain due to him having a book called the Gilded Age‚ which satirized American society in the late 1800s. It was a time of government corruption‚ poverty‚ and awful labor conditions but it being covered up by big businesses‚ or “gilded”. Progressives were people who were advocating social reforms such as the prohibition of alcohol

    The Progressive Movement (1900-1920) was basically a reform movement. The movement drew its ideals and inspiration from the writings of Thomas Jefferson and reform groups that had attracted some attention in the 19th Century. The progressives were successful in part because they were able to rally the better part of a generation to their ideas about reform. While not all progressives supported all progressive reforms‚ the basic objectives of the movement included the following: Destruction of the
