Experiment 4: Projectile Motion

Introduction:
Projectile motion is a special type of motion involves two components of motion – horizontal and vertical. But motions in two directions are independent of each other. Flight of ball is an example of projectile motion. This two dimensional motion can be determined as two linear motions in two mutually perpendicular directions –one along horizontal direction and the other one along vertical direction. Projectile motion can be analyzed with the help of equations of motion. Vector equations and vector rules are generally used as the motion occurs in two dimensions. Gravity force has primary importance in projectile motion. Effect ...

The Simple Pendulum

Introduction

The aim of this experiment was to experimentally find the time period of a simple pendulum, and use to compute the local acceleration due to gravity. These values were compared with the theoretical predictions based on the equation, =2πLg , where T is the time period, L is the effective length of the simple pendulum (measured quantity) and g is the local acceleration due to gravity. In order to compute the total error between the predicted and actual values, the effects of all random errors in each measured quantity ...

Experiment 2: Motion in one dimension

Introduction:
Motion of a body in one dimension is basic study in physic and to have knowledge about motion in one dimension it is necessary to be acquainted with two fundamental laws of physics. One of them is Newton’s laws of motion and another is Newton’s law of gravity. There are three laws in Newton’s laws of motion, but in this paper only Newton’s second law of motion has been discussed. If force is applied on a body, the same will move as a result of applied force on the body. The body will remain in same ...

Chapter 4: The Origin of Modern Astronomy (Summary & Reflection)

Chapter 4 of “Astronomy: The Solar System and Beyond” starts with a description of the geocentric view that that the Early Greeks held of the universe. It was Aristotle’s conclusion that the Earth is spherical in shape. In A.D. 140, the Ptolemaic system, a more refined form of the Greeks’ geocentric view, was presented by Claudius Ptolemy. According to Ptolemy, the planets orbited the Earth in epicycles or small circles. It was Nicolaus Copernicus who proposed that the sun is at the center of the universe and the plants orbit around it. Tycho Brahe made the most precise astronomical observations ...

Introduction
Specific gravity is the comparison ratio of the mass of a model to the one of an equal volume of the standard substance. Specific gravity is an intensive characteristic of material. The same property can be used for analysis of velocity and other aspects of engineering design. In this experiment, the specific gravity is the ratio of the mass of a unit volume of a given soil sample at a certain temperature to the mass ...

Physics 11 Experiment 3: The acceleration due to gravity

Introduction
The free fall movement is not a steady movement because there is an action over the body due to the gravity or acceleration between two bodies with different mass. The moon and the earth exert an attraction force due to their two masses (University of Tennessee Knoxville). The planets of the solar system have an orbital movement around the sun thanks to attraction force due to the mass of the sun and the planets. All the particles and bodies in the universe attract them. There is a general equation that represents that phenomenon:
F = G*m1*m2/r2
Where ...

Introduction

As the globe is getting smaller every day, the trade between countries is increasing every day. There was a time when each country tried to become self-sufficient to sustain on its own. Those days are gone now. Now, a country needs to be efficient in one so that it can export it to others and in return buy things from others in which they are efficient. In this way both benefit.
International trade is one of the biggest financial and economic areas for any kind of research. Economists always try to find out the factors that drive international business. Is ...

Problem Statement - What are the accelerations produced by varying forces on a given mass?
Hypothesis - If the force on a cart with a constant mass is decreased, then the acceleration will be greater

In this experiment Newton’s second law of linear motion was being investigated. A cart was connected by a ticker tape and a ticker timer used to get the velocity and time. The hypothesis was that a decrease of the force on a cart with a constant mass results in greater acceleration. This is because removal of certain masses results in an equivalent resultant force, hence more resultant force causes more ...

Patterns of Surface Ocean Currents

Surface currents are found in the upper four hundred meters of an ocean body and they form major patterns such as eddies, upwelling, and gyres (Garrishon, 2007). Surface currents result from wind energy that is concentrated in both north and south hemispheres forming trade winds which are easterlies and westerlies (Garrishon, 2007). Waves on the sea surface transfer some of the energy from the moving air to the water by friction. Pulling of wind on the surface of ocean causes an accumulation of water with the water displaced underneath the wind forming the movement.

Introduction

When a ball rolls off a table, gravity will act on it and pull it down towards the ground. While the ball is rolling over the table, it has an initial velocity that is horizontal in direction before it leaves the table. As it leaves the table and gravity starts acting on the ball, it will follow a parabolic trajectory as shown in the following figure.
Figure 1 : Ball Rolling Off a Table Path of Motion
The first problem is how to find where the ball will bounce off the ground the first time. The second problem is ...

Abstract

In this experiment, the young modulus of three beams was investigated these were steel, aluminum and timber. The beams were placed and the deflections values upon addition of various loads at the Centre of the beam taken. There was a variation of the loads across the beam to investigate thee relationship that existed between the loads, the span width, height, and deflections. Measurement of the deflection was therefore done through the dial gauge with three sets of measurements being taken and the average calculated. Different beams were used to enable elaborate comparison of the coefficient of elasticity. Measurement of ...

Abstract

Concrete acts as one of the most essential and cost-effective construction material made from a mixture of sand, cement, aggregates, and water. Cement acts as a binder for holding all the components together. Engineers working in the construction site must understand the purpose of the construction because different structures require different concrete strengths. The strength of cement paste used controls the overall strength of concrete that depends on the water-cement ratio. The following experiment was conducted to investigate different mechanical and physical properties of concrete.

Objective: To determine mechanical properties of concrete.

Materials used: Aggregate (coarse and fine), sand, cement, water, compressive machine, cylindrical and rectangular molds, timer, ...

Our modern thoughts on science were brought about by what is known ad the scientific revolution. It transformed the fields of all the sciences including, mathematics, physics, astronomy, biology, medicine, and chemistry. Many believe this period in time began during the renaissance in Europe and continued on through the 18th century. Two main figures in the scientific revolution were Sir Issac Newton, who was an English physicist and mathematician, and Galileo Galilei an Italian physicist, mathematician, astronomer, and philosopher.
Galileo Galilei was born in 1564 and was an Italian mathematician and physicist. His work included the construction of a ...

Introduction

Newton's Second Law of motion asserts that the acceleration of an object exhibits a direct proportional relationship with the subsequent force acting on it. It explores the relationship that exists between force, mass and acceleration as exhibited by an object. This experiment examines Newton's Second Law of motion by enabling a dwindling weight to speed up a glider of recognised quantity along a track. A thread that links the dwindling mass to the glider is passed above a smart pulley (Knight, 2004). It is imperative to note that the smart pulley exhibits insignificant inertia, low friction and its revolution ...

Abstract

The experiment involved the investigation of the young’s modulus of different beams made from different materials. The beams that were used for the test were steel, aluminum and timber. The experiment involved placing of the beams on the measurement machine shown below and addition of loads at the center of the beam. The loads were then varied across the beams while investigating the relationship that existed between the beams when different loads were added. The height, width, and the respective deflections were therefore recorded for analysis. The dial gauge was used to measure the deflection of the beam ...

Wave and Wind Power Generation

Wind Physics Basics
Wind is atmospheric air which is in motion
Energy Source
The earth surface absorbs solar radiation differently. Some parts absorb more radiation than other. This creates pressure zones. As a result of pressure, air moves from high-pressure zones to low-pressure zones. This causes atmospheric air motion known as wind. Wind is a renewable source of energy. It is constantly available free of charge (Bhattacharyya, 2011).

Spatial scales

Atmospheric air motion can be categorized depending in terms of spatial scale. Four spatial scales identified include planetary scale, synoptic scale, mesoscale, and microscale. There are various types of spatial scales ...

Introduction

When objects are accelerated, inertia-forces are generated. This is the case with rotating machine elements. The design of such parts must ensure that they perform their intended work under all the existing combinations of service loads and rotational forces or inertia forces. The rotation of a machine element results in an external vibrating force. The shaking force disturbs the supporting frame of the machine and the adjacent parts. It is also worth to note that the vibration generated by rotating machine elements and consequently the associated noise is also a serious problem to the machine operators. Therefore, it is very important ...

The theory of plate tectonics describes the wide­scale movements of the lithosphere of

the earth. The model is based on the ideas of continental drift, which first gained acceptance in
the early 1900s. The geoscientific community granted the theory even more validity after the
notion of seafloor spreading appeared in the late 1950s. Basically, the lithosphere is not whole
but instead is separated into either seven or eight major plates, depending on the definition that
you use. Every meeting point between plates has its own relative movement, either transform,
convergent or divergent. Volcanic activity, mountain creation and earthquakes all occur along
these edges, and the plates ...

Introduction

The cardiovascular system consists of arteries, capillaries veins blood vessels and the heart. The heart delivers nutrients and oxygen to the tissues and caries waste products for elimination from the tissues (Hester & Lusha, 2012). The regulation of the cardiovascular system occurs through a complex interaction of both neural and non-neural mechanisms that aim at guaranteeing a constant internal environment (homeostasis) in organisms (Malliani 2000). The regulation of the cardiovascular system occurs through hemodynamics, through auto regulation, hormonal regulation and neural control (Khurana, 2008).
The most important of the regulatory mechanisms are closed loop reflexes like baro- reflexes, chemo reflexes and ...
