The Meaning of Conservation Proper use of resources and strict compliance with the rules on conservation are the keys to protecting and conserving our limited resources. Conservation is the act of using and protecting resources properly. Catching animals‚ throwing garbage‚ and using and harnessing the different resources should all adhere to the proper way of conservation. Importance to Living Things. Conservation is very important to all living things. The environment where

Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body‚ following a curved path‚ has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum. Torque is the angular "version" of force. The units for torque are in Newton-meters

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

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

the final momentum resulting in an unusable attempt. 3. Discuss any differences in total momentum before and after the collision There were small amounts of differences in momentum before and after the collision‚ this can be related back to random and systematic errors throughout the experiment such as the equipment being slightly off. There is also energy lot through the form of sound and friction of the wheels. Introduction: This experiment explores the conservation of momentum and energy

For each problem (momentum‚ energy & mass)‚ we will start with an initial chapter dealing with some results of the molecular theory of the transport phenomena (viscosity‚ thermal conductivity & diffusivity) Then‚ proceed to microscopic level and learn how to determine the velocity‚ temperature and concentration profiles in various kinds of systems. Then‚ the equations developed at microscopic level are needed in order to provide some input into problem solving at macroscopic
