Essays on Physics

Traditional Training vs Contemporary Training Traditional training entails a series of teachings, both theory and practical, where the trainer and the trainees enjoy personal touch or the physical presence of each other. On the other hand, contemporary training is an evolutionary way of teaching or coaching which makes good use of...

An electric circuit is a system of a conducting path together with a source that creates potential difference in order to maintain the flow of charge. Two of the important characteristics of any circuit are the amount of charge that is flowing and the potential difference that is maintained by...

Consider a boy throwing a tennis ball in air through an angle; in a range that is fructose induced. Figure 1below shows the path taken by the ball through space. In our case scenario, the tennis ball is considered as a projectile that is two-dimensional. Such is due to the...

Cooling fans are supposed to bring fresh air into the room. They are designed to rotate using a motor. However, this fan uses electricity to function. Cooling fans can be more useful if they are used to light our rooms by converting the mechanical energy produced by the motor to...

Hooke’s Law explains the behaviour of the spring and other linearly elastic objects. According to the Hooke’s Law, the stress is always directly proportional to the strain. The aim of the Hooke’s Law experiment was to investigate and verify Hooke’s Law and the acceleration due to gravity with a linearly...

When a circuit is closed, the potential difference causes charges to move within the circuit thus constituting current passing through various appliances to perform designated functions. The electrical power generated from the power source is not all utilized as desired as some of the power is lost in the form...

In industrial nations, there are small communities that lack access to adequate supply of energy. The essay focuses of Teesdale community. Apparently, communities in the industrial regions have significant demand and community engagement. Teesdale community is used to demonstrate energy poverty. The energy demand is assessed and suitable sources selected....

The American economy depends largely on fossil fuels like coal, natural gas, and oil. According to Maczulak (2010), America uses more energy than it can produce; hence, it must import to meet the deficit. Despite offering immense benefits to the Americans and indeed other nations of the world, the burning...

Recent statistics depict that there will be an increase in reliability of alternative sources of energy by 2020. At least 26 percent of the total primary energy will come from alternative energy sources (Intergovernmental Panel on Climate Change). This trend has been established based on analysis of a pattern of...

Snell’s law or the Law of Refraction is .Consider a light ray which travels from fixed points P to Q. The ray will choose the quickest route (through the point X, which is not fixed) and so minimize the time of travel. The light ray has velocity CA in medium...

There are several methods used in angular measurements as discussed in this paper. Albeit the standard magnetic compass has been used to give approximate values of angles, it has several inherent problems such as the inability to correctly align with the earth's rotational axis. As a result, more efficient devices...

Density can be defined as the mass of an object per unit of its volume. This implies that mass and volume are the elements of an object’s density. Mass is the total amount of material an object contain while volume is the total space that that object occupies. The SI...
