The Extension of an Elastic Band Aim & Hypothesis I anticipate that an increase in the load on the elastic band will result in an increase in the extension of it. I think that the extension will be proportional to the load on the elastic band. I think that there will be a certain amount or energy lost and that this will increase proportionally as the load increase. This will be lost due to heat energy. Safety RISK ASSESSMENT - LEVEL ONE This experiment does not carry many hazards
The Effect of Applying Weight to an Elastic Band and How it Affects the Length it Stretches To Aim In this coursework I will be investigating the effect of applying weight to an elastic band and how much this affects the length it stretches to. This will also involve the use of Hooke’s Law and the Simple Harmonic Motion. I will do in-depth research on Hooke’s Law and how the force applied affects the change in length of a material. The apparatus I will be using is listed below: 1
work and research on the Internet I have gained some knowledge. This will help me carry out my experiment and understand it. Equations --------- Work done (j) = force applied (N) x distance (m) The previous equation also applies for Elastic Potential Energy. Acceleration (m/s²) = force (N) mass (kg) Forces ------ Friction = the force which resists movement between two surfaces that are in contact. Gravity = the force that pulls objects towards the Earth. Air resistance
would have lengthened, and for a rough surface, the sd. would be shortened. If a margarine tub uses a stretched elastic band to catapult it forwards, then the amount the elastic is pulled back determines how far the object travels before stopping. When the elastic band is pulled back then it has Elastic Potential Energy (EPE) which is changed to kinetic energy (KE) when the band is released.
to achieve: I believe that the purpose of doing this is to allow me to demonstrate my understanding of Elastic potential energy. And the projectile concepts of the effect of changing potential into kinetic energy and for me to demonstrate my ability to apply elastic potential energy to a scientific investigation. What am I going to do and what will it prove: I am going to use an elastic band and release it from different tensions I will then measure how far it ‘flies’. Doing this will
face-down on the folding surface and smooth out any folds. You can do an extra neat job by pulling gently on the side seams to smooth out the back. Now start folding. Fold the shirt lengthwise along the line of the outer edge of the collar or neck band. Smooth the sleeve out, using your fingers to pull at the seam, making it slightly taut. Fold the other side over. Fold it lengthwise, along the line of the outer edge of the collar. Repeat the sleeve-smoother technique. Fold the shirt in half. Take
piece of elastic stretches when a load force is applied and the amount by which the stretch is reduced when the load is removed. Aim (in simpler terms): To determine the relationship between the force on a rubber band and its stretch, both during extension and retraction. Hypothesis: Not required. Method 1) Hang a piece of elastic on a clamp stand. Ensure the elastic is new. 2) Clamp a ruler using the clamp stand. Ensuring the markings on the ruler is as close to the elastic as possible
over a bowl held by a rubber band. The materials that I used in this experiment were six different bands of paper towels; Scott, Giant Eagles “Clean and Tuff”, So- Dri, Brawny, Viva, and Bounty. I also used twelve 88.7 milliliter dixie cups, 50 milliliters of red colored water and a freezer holding the temperature of a negative twenty degrees Celsius. In addition I used a plastic bowl with the dimension of 18 by18 millimeters. And finally I had a piece of elastic string. The procedure for my
rotation. Here the focus will be on collisions between the balls. The spin can have a significant effect on the motion of the ball, but due to time constraints and complexity of the science of it it will not be addressed to much detail. "An elastic collision between two objects is one in which the total kinetic energy (as well as total momentum) of the system is the same before and after the collision." (Physics for Scientists and Engineers) In a collision between the cue ball and another
The term globalisation is a particularly elastic concept. Not only does it embrace a wide range of ‘things’, it also straddles the realms of ‘fact’ and ‘value’ of ‘idea’ and ‘reality’, thus to define the word globalisation requires an amalgamation of both moral and material values which may include and encompass events as dynamic as economic, political and social. At its simplest globalisation has tended to denote the idea that societies are becoming increasingly affected by events of other societies
Federalism, by definition, is the division of government authority between at least two levels of government. In the United States, authority is divided between the state and national government. “Advocates of a strong federal system believe that the state and local governments do not have the sophistication to deal with the major problems facing the country” (Encarta.com). Even before the Constitution was ratified, strong argument were
Transport in Mammals A recurring theme in biological systems is the surface area to volume ratio. All cells require nutrients and most require oxygen as well. Wastes also need to be removed. With a small organism this demand can be met by simple diffusion over the body surface but larger or very active organisms need a transport system with a pump to ensure that the supply meets the demand of all cells, even those deep within the body. In mammals, the pump is
exactly fit the data. A non-probabilistic analogue of the confirmation condition above that I offer avoids the 'old evidence problem, which has been a headache for classical Bayesianism. Idealizations and approximations like point-masses, perfectly elastic springs, parallel conductors crossing at infinity, assumptions of linearity, of "negligible" masses, of perfectly spherical shapes, are commonplace in science. Use of such simplifying assumptions as catalysts in the process of deriving testable predictions

cardiologist is often able to treat coronary disease before it causes an MI. – http://myweb.com/contents/dmk_article396168 Coronary Artery Disease Healthy arteries are flexible, strong, and elastic. Their inner layer is smooth and blood flows freely. As you get older, your arteries become thicker, less elastic, and deposits build in them. This leads to a general hardening of the arteries, which is also called atherosclerosis. Atherosclerosis or arteriosclerosis is the main cause of coronary artery
Price elasticity of demand is defined as how demand changes as a result of a change in price. It can be said that if a reduction in price leads to an increase in demand then demand is relatively elastic. Elasticity is usually negative. There is an alternative scenario where demand will increase as price does so too. This happens only in the case of Giffen goods, where elasticity is positive. The formula for price elasticity of demand is: Percentage Change in Quantity Demanded Percentage Change
Nike is a huge supplier if athletic shoes for the world these days. Philip H. Knight, the founder of this corporation came up with an idea of an athletic shoe at the track field of the University of Oregon. Now it has become a leader in the global economy. Nike has helped the economy by employing more than 500,000 people, worldwide. The company has contributed in finding a positive policy for minimum wage. Minimum wage laws usually don’t help who they’re originally set out to. Now with Nikes’ minimum
improvements throughout the years. A team of DuPont researchers, led by Dr. Wallace Hume Carothers, invented the first synthetic material, nylon, in 1934 (Adams 21). They were searching for an artificial replacement for silk when they drew out an elastic string from plastic, creating nylon. There are two popular ways of creating nylon for fiber applications. One, ¡°molecules with an acid (COOH) group on each end are reacted with molecules containing amine (NH©ü) groups on each end.¡± The nylon 6,6
purposes we can just look at the following equation which relates kinetic energy with mass and velocity of an object. K = ½mv2 where K = kinetic energy When you strike another ball with the cue ball it is almost a perfect elastic collision. An elastic collision is one in which total kinetic energy as well as total momentum are conserved within the system. This can be shown by the two basic equations; Conservation of Kinetic Energy: ½m1v1i2 + ½m2v2i2 = ½m1v1f2 + ½m2v2f2
involves the economic concept of price elasticity. Therefore the first aim of this essay is to outline the concept of the price elasticity of demand. It will be focused on 3 aspects, first, definition of the price elasticity of demand, second, elastic versus inelastic, and finally some factors influencing the price elasticity of demand will be interpreted. Also in this essay, it will be discussed that the price elasticity of demand in health care market. The price elasticity of demand measures
