The Use of Electricity and Magnetism in Transportation

The Use of Electricity and Magnetism in Transportation Introduction The use of electricity and magnetism in our future transportation has formed a subject of debate and research for many decades. As early as 1840s, the first linear motors were developed. A breakthrough in this technology was achieved in 1935 when the first practical linear motors were developed in Germany (Kirkland, 2007). Linear motors are important in enhancing magnetic levitation in modern high speed trains or what is referred to as Maglev trains. This essay will first analyze how the Maglev trains work and then explore how the concept can be applied for future transportation not only in trains but also in road systems. Magnetic levitation has generated a lot of interest among many countries. In this system, electromagnets are used to create strong magnetic fields. The strong magnetic fields levitate the maglev trains above the track. This is in accordance to the magnetic principle which states that the like poles of a magnet repel...

Conduction, Convection and Radiation

Conduction, Convection and Radiation

Name Professor Institution Course Date Conduction, Convection and Radiation Heat is a form of thermal energy that can be transferred from one point to another. Heat transfer takes place through conduction, convection and radiation. Heat generally flows from a hot object to a colder one. This process continues until the two regions with temperature differences achieve a thermal equilibrium, and as long as the external source of heat is removed (Sundén, 2012). All metals are good conductors of heat. On the other hand, gases and non-metals fall into the category of poor heat conductors. These are also referred to as insulators. Heat conduction involves heat transfer within the object itself, while radiation may involve flow of heat between objects that are separated spatially. Heat transfer through convection occurs through a material carrier that facilitates flow of heat energy.  This paper will analyze in detail the above mentioned heat transfer mechanisms, giving relevant examples. Conduction According to Baukal (2012), heat conduction is the flow of thermal energy between objects...

Use of Physics in Daily Activities

Use of Physics in Daily Activities

Name   Institution   Use of Physics in Daily Activities Physics can generally be defined as a science that involves the study of forces and their interaction with the environment. Precisely, physics is the study of matter, energy, time and space, and how they interact with each other. Physics assumes the existence of four basic units which include: length, mass, electric current and time. These quantities are measured in terms of the metre, kilogram, second and Ampere respectively. According to physics, the four basic units are used to explain all other physical quantities.  Physics is used to explain how things move, and to analyze the forces that hold them together and/or forces that make them move. As such, it is hard to imagine modern life without application of physics in the daily activities. This paper will analyze the use of physics in daily activities, giving simple activities where physics is applied on a routine basis. Communication Physics is greatly used in communication. Communication may be carried out...
