Air resistance is an opposing force often known as drag force. Air resistance acts in the opposite direction to snow skier’s velocity and can either harm or enhance performance of the athlete. The flow of air around an object causes the unavoidable effect of drag and is influenced by the size‚ shape‚ surface‚ and overall speed of an object (John Polson‚ 2013). Air resistance is present in snow skiers and can inhibit their performance in a race greatly if the proper precautions and positions are

Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light bulb. How is it measured? The resistance of a length of wire is calculated

Peaceful resistance‚ as with all forms of protest‚ have both positive and negative effects on America’s concept of a “free society” but upon inspection‚ one can see that in time‚ it is positive. Forms of peaceful resistance can range from a conscientious objection to a law in the form of protesting‚ to simply writing a representative to express one’s opinion on a law. Each of these are opportunities for citizens to exhibit their constitutional rights to organize‚ free speech‚ and perform their civic

Planning In this piece of coursework‚ I am going to investigate what affects the resistance of a piece of wire. Wire is made up of atoms. Electric current is a flow of electrons‚ and it is these electrons that collide with the nucleus of the atoms. Every time this happens‚ it causes resistance. The build up of friction is what produces the heat. There are many variables that could affect the resistance of the piece of wire: Length Potential difference Tension Temperature Diameter

development of increased resistance to antibiotics is a global concern. According to WHO (2015)‚ antimicrobial resistance is an increasingly serious threat to global public health that requires action across all government sectors and society. Antibiotic resistance threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria‚ thereby resulting to loss of the ability to treat common infections. The development of antibiotic resistance is a natural phenomenon

reduce resistance to change 1. Using Lewin’s Change Model‚ successful unfreezing can set the stage for change to take place. <INSERT CONTEXT: why is the change needed?> By understanding the need to change‚ employees become dissatisfied with current practices‚ hence motivated to change. The organization must always create the motivation to change. This creates favourable predisposition towards change‚ reducing resistance. 2. From Kotter’s six strategies to overcome resistance to change

There were many resistances from slaves‚ violent and non-violent‚ during the period of slavery in the BWI. Violent resistance was in the form of revolts and rebellions and non-violent resistance included actions such as suicide‚ poisoning‚ avoiding work and maroonage. However‚ there were three violent resistances which stood out. These three were Bussa Rebellion in Barbados (Easter 1816)‚ Demerara Revolt in Guyana (August 1823) and the Sam Sharp Rebellion in Jamaica (December 1831). These rebellious

There are many tactics to get a point across. Some will use violent ways and others will choose to do peaceful resistance. Peaceful resistance positively impacts a free society. Martin Luther King is an example. Martin Luther King JR‚ definitely made an impact and got his point across. Many people joined his peaceful protesting and he got a lot of respect even today. By doing no harm‚ it it is a super effective way as it shows that the people are respectful and not monsters or savages. It gives them
