Essays on Physics

This lab primarily aims at investigating Newton’s laws of motion. It involves the experiment on mass, velocity, time, and the acceleration of a cart. The experimental values of acceleration are compared with those of the theoretical ones. Theory The lab involves experimenting with a cart that is self-propelled using a fan. Other...

a) A thermometer is a temperature measuring device and even though there are various types such as the mercury and alcohol they all have the same basic features. A liquid-in-glass thermometer is made up of a bulb, capillary, scale, and an expansion chamber. The scale of...

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...

Hollywood is notorious for movies that stretch the laws of physics for the sake entertainment and commercial purposes. To illustrate how these laws are defied, for example in the fictional film The Matrix several scenes defied these laws especially the first law of Newton s motion. This is a science...

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...

This paper is a lab report for an experiment on the calibration of a differential pressure transducer. Through this experiment, we will be able to measure the accuracy of the differential pressure transducer. Ideally, this equipment works in accordance with the principle of static differential pressure measurement. The pressure transducer...

1. Thermal Physics 1.1 Change of Pressure with Altitude and Temperature p = Given, T = T0 –az; (K) for z 11,000 m a = 0.00649 K/m a) From the equations of the aerostatic and the perfect gas law, we can write, p = ρ R...

(a) An AC voltage is described by the equation 푣 (푡) = 푉cos(휔푡 + 휙). Sketch this voltage waveform, and explain the meaning of terms 푉, 휔, 푡 and 휙. Sketch of the voltage waveform. V   The maximum or peak value of the voltage 휔   the angular frequency expressed in radian...

Newtonian laws have become a handful in illustrating the relationship between forces and motions. The type of relationship that exists between the two is counter-intuitive and as such needs a careful review as well as an explanation. The first law suggests that a body will remain static or continue in...

According to Christensson (2016, par 1), a diode is an electrical component that is designed for unidirectional conduction of electric current. A diode has two terminals with each end having an electrode that bears a different charge. One side of the terminal referred to as, an anode, has a positive...

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....
