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

technological momentum as a point between two opposite ideas; social constructivism and technological determinism. This raises questions as to what exactly the relationship is between technological momentum and soft determinism. Both ideas deal with the effect society has on technology and the effect that technology has on society. I will argue that while both ideas seem to be the same‚ there are important distinctions to make between the two. One is that Hughes’s idea of technological momentum is time

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

articles focus on anomalies that should not hold true in an efficient market and other articles try to dispel those anomalies. 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. Momentum Jegadeesh and Titman 1993 aimed to investigate the returns on stocks that had previously performed well (winners) and sell stocks that had previously performed

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

Lab 5 Conservation of Momentum and Energy Abstract The physics laws governing conservation of momentum and mechanical energy were investigated by performing multiple experiments with differing conditions. Conservation laws state energy is to be conserved in systems with no net external forces. Two trials consisted of inelastic collisions and two trials consisted of elastic conditions. Photogate software helped decipher initial and final velocities in order

Beauty and the Creative Impulse This essay‚ out of the three‚ was my favorite. The author had a lot of good points to support her thesis in which she stated that beauty is something integral of the world we live in; the earth that the Creator created. She also brought up the fact that sometimes we move so fast that we take beauty for granted. In this day and age‚ we live our lives in fast forward and we‚ almost literally‚ do not even attempt to stop or even slow down to smell the roses. She
