Collision Reports Samples For Students

Introduction and Theory

The main aim of this experiment is to investigate energy and momentum conservation in a closed system. Momentum and energy conservation principles are significant physical variables that engineers use when describing various physical phenomenon. Momentum of a body is a vector quantity, which is given by the product of its velocity and mass. In collision theory, the momentum of the body is always conserved when two bodies collide. The principle of momentum conservation applies to both elastic and inelastic conservation irrespective of the dynamic interaction between the two objects. This report demonstrates the application of momentum equation in determination of motion parameters ( ...

A collision refers to a physical situation where kinetic energy of momentum of an object is transferred from an object to the other one. In physics, collisions are classified as either elastic or inelastic. Conservation laws; energy conservation and momentum conservation are important tools in the analysis of collisions. Various literatures and experimental studies have confirmed that it is difficult to assess the interaction of bodies during collision. Therefore, main objective of this work is to demonstrate to relate the various parameters such as velocities and masses of the system using the principle of conservation of energy and momentum.

The momentum of an object of mass, m and velocity, v is represented mathematically as shown below:

Experimental Data

Data Analysis
In two dimension collision, the momentum and kinetic energy before and after collision should be equal. The law of conservation of energy stipulates that the energy before and after collision should be equal, especially if there was no lost energy. However, in reality, some energy is converted into other forms of energy, hence ...

Introduction

In any collision, where the system is not subject to external forces, linear momentum will be conserved. In case the collision is elastic, kinetic energy will also be conserved. In this experiment, two steel balls were made to collide momentarily, and the projection of their 2D collision dynamics was recorded for analysis. The vectors measured using the carbon paper, are related to the momenta of the balls before and after collision. These were used in the respective equations to verify linear momentum conservation and elastic collision, i.e. kinetic energy conservation.

Vitamin C Clock Reaction: Kinetics

Abstract

Collision theory refers to a theory that was proposed by Max Trautz and William Lewis independently. The theory qualitatively offers an explanation on the way chemical reactions take place and the reason behind differences in reaction rates in different reactions. The rate equation for a given chemical reaction refers to the equation that provides a link between the pressure or concentrations of the reactants and the parameters that are constant partial reaction orders and the rate coefficients. This experiment aimed to determine the rate of reaction of reaction between iodide and hydrogen peroxide and determine the order ...

Objective

The purpose of this experiment was to examine the impact of two hockey pucks in an inelastic collision and to confirm that momentum and energy are almost entirely conserved, allowing for the inherent errors involved in the observation process. The law of conservation of energy states that during a collision, energy can neither be gained nor lost, but can be transferred or transformed. During an elastic collision, the energy and momentum is transferred from one object to another. Unlike in an inelastic collision (such as the kind seen in the previous laboratory experiment), we expect kinetic energy in an elastic ...

1. The average values of hi, hf, y, and X were found to be:
hi = 5 cm
hf = 15.87 cm
y = 104.84 cm
X = 310.235 cm
2. h = 15.87 – 5 = 10.87 cm
3. Using equation (10) to determine the initial velocity and equation (11) to determine initial momentum, we find
vi = 3.10235*sqrt(9.81/2*1.0484) = 7.035 m/s
pi = 0.06944*7.035 = 0.4885 kg m/s
4. Using equation (7) to calculate the final momentum of the system, we find
pf = (M + m)*sqrt(2*g*h)

Final Assignment

Both Bridges and Switches work on the data link layer of the OSI Model. However, switches are more advanced. Discuss how a switch has an advantage over a bridge in a network then elaborate more on the technology implemented in switches to control broadcast domains
A bridge is a two interfaces device that creates two collision domains. This is because it forwards the traffic received from one interface only to the interface where layer two devices is connected (Olenewa, 2014). Bridges serves the main function of reading the destination of MAC address to forward the traffic only to the interface where it ...

Introduction

The sinking of the Titanic is one of the worst sea tragedies. The cause of the tragedy is believed to have been a collision with an iceberg in the near-freezing Atlantic Ocean, but forensic investigations revealed more flaws in the design of the ship. The ship was inadequately equipped with lifeboats and had initial design flaws which resulted in water flowing from one watertight compartment to another. Moreover, there were communication flaws which meant that distress calls could not be received quickly while other findings revealed that some of the structural components were too weak to sustain the freezing ...

Cryptosystems have various challenges that render them vulnerable. Since the cryptosystem ensure data security and integrity, the weaknesses of such systems are very critical. The MD5 SSL has a critical vulnerability in that it is possible for one to create phishing sites that have valid SSL certificates. Such vulnerability is most probable using the HTTPS. In this case, the SSL certificates are made from an existing one using hash collision. Therefore, the users would think they are connected securely, and authentically while in actual reality they are connected to the attacker.

Introduction

An enzyme refers to a molecule that is protein in nature and works as a biological catalyst. The enzyme possesses three major characteristics. The first characteristic is that they act to increase the rate at which a given reaction takes place. This enables most cellular reactions to take place at up to million times faster compared to their rate in the absence of an enzyme. Secondly, most enzymes act specifically on a single reactant known as a substrate to produce the ...

A better understanding of thermodynamics may be achieved by understanding the general molecular structure of matter as it exists in water and steam. Molecules are the smallest amount of the compound material that has complete chemical traits of that element, which can exist. Molecules consist of smaller particles that define basic elements called atoms. Most minerals constituents can exist in solid, liquid and vapor states called phases. The three phases of a substance can only coexist in equilibrium at a given temperature and pressure. In the liquid state, the molecules can move, but they are still one molecular diameter apart to ...

Introduction

Faster travel time, a feat of human imagination and a masterpiece of engineering. These are but some of the things that airplanes embody in the world. While there have been many records and variations throughout history of emulating flight, it was the Wright Brothers that finally made modern aircrafts possible back in 1903 . Since then the “aeroplane” has been used in many situations of human history. Such situations include public transportation, combat and even entertainment.
This invention did not come without a price however; just as when dynamite was used in manners that were against the wishes of Alfred Nobel (leading ...
