Introduction

The purpose of this experiment was to observe collisions between two carts, measure energy changes and classify the collisions. It was hypothesized the momentum would be conserved during the collisions.

- Consider a head on collision between two billiard balls. One is initially at rest and the other moves towards it. Sketch a position vs. time graph for each ball, starting with the time before the collision and ending a shot time afterward
Before collision, ball 2 moves with a constant velocity towards ball 1. Therefore, its position changes with time while the position of ball 1 does not change. After elastic ...

Heat and Temperature

The transfer of energy from a high temperature body to a lower temperature body is known as heat. Heat travels in form of waves and like any other form of energy it has the potential to bring change into the matter it contacts. This process is usually accompanied by the transfer of entropy, the energy per unit temperature that goes unused. Heat transfer is usually generated by three types of thermal interaction, mainly, conduction, convection and radiation. Conduction is mostly related to the transfer of heat in solids, wherein the materials are in direct contact with each other and the heat ...

We have all been taught how every object and thing around us is made up of matter and that matter exists in three very basic states which are the solids, the liquids, and the gasses. Even within these solids, liquids and gasses are particles, and it is simply the arrangement of these particles which makes any matter form one of the three states. It is also because the major difference between the three states is how the particles behave around one another which make the transition possible in between one state of matter and the next.
In simple words, ...

Introduction

Enzymes are proteins which have the ability to facilitate metabolic reactions without being used up in the reaction. The enzyme amylase is responsible for facilitating the hydrolysis of starch to form sugars that are then assimilated by the body. Amylase is an enzyme needed for the digestion of carbohydrates for nutritional purposes. Starch is one of the most important sources of energy in the body. Starch is a polymer made up of several monosaccharide and disaccharide monomers. However, starch cannot be absorbed and used in the body as it is (Cornish-Bowden, 134). Consequently, it has to be digested into smaller ...

The gadget is a wind power harnessing device that is small enough or can be taken down, packed up and moved with easily. The generator is powerful enough to provide energy for charging smartphones and other USB devices (Kleinschmidt, 2008). The operation principle for portable wind turbine generator is less the same that of large wind turbine generator.
The device comprises of a drive train that has the main shaft, a hub, ...

The law of conservation of momentum states that the total linear momentum of a system remains constant. Bodies under collisions exert equal and opposite forces, however, in the absence of external forces, their change in momentum is equal and opposite. There are two types of collisions: elastic and inelastic collisions. In elastic collisions, both the total kinetic energy and momentum of the colliding bodies is conserved. On the other hand, only momentum is conserved in inelastic collisions. In the latter, bodies fuse together after collision (Wilson and Hernandez 129).
The experiment investigates the conversation of linear momentum in an ...

Radiation in space and material bodies, are mostly referred to as thermodynamics system. Thermodynamics can be therefore be described succinctly as the ...

Introduction

Track and field is a set of games in various levels that includes games such as long distance running, sprint, javelin throw and shot put. The history of these games is believed to have originated from Greece (Weebly). In these games, there are several concepts of physics that are applied with the most notable ones being speed, force, kinetic/potential energy, acceleration, friction and momentum.

Speed

This can be defined as the act of moving fast or in a swift manner. The equation is given by Speed = Distance travelled/Time. If one is running on a track during a competition, it is ...

Introduction

Energy is a key driver of any nation’s economy. The extent to which it contributes to the performance of all activities surrounding the human life is beyond measure. This is because energy contributes almost fully to the economic development of the economy. In its physical form, energy is classified either as renewable or non-renewable. Renewable energy forms the green energy that can be reused again and is less toxic to the environment. On the other hand, non-renewable energy is exploited once it’s used and mostly pollutes the environment. All this energy forms can be either used directly ...

Additionally, the turbine technology is more efficient. This is because it can employ a number of fossil fuels, water, geothermal energy or wind to generate electricity. Hence, the country has a greater variety to choose from ...

Assignment 1

Energy refers to the ability to produce changes in a given system and it exists in different forms, but it is broadly categorized into two major forms which are Kinetic energy and Potential energy. It is further grouped into many other forms that include; heat energy, light energy, mechanical energy, sound energy and geothermal energy. Energy is converted from a given form to another depending on the energy needs of the user. This transformation simply implies conversion of energy from one state to another, which may occur naturally or it can be manipulated using various energy-consuming machines. In scientific terms, a device ...

The heat was intense. The orange light shone on the desert, drying up the remaining puddles of water into vapour, rising into the atmosphere. A lizard crawled slowly, almost dying, parched and with a hide so leather like, one would think it was crisp fried.
Slowly, I heard the intense ringing of the siren. Waaang waaaang waaang. It was time to get inside our shelters. The shelters were not made of concrete. Unlike the olden days, concrete was the material of choice. All buildings were once made from stone, from cement mixed with water to form hard solid blocks. ...

Engineering

Retrus, Maimane and Mosoallbisi (2014) agree that mechanical energy is the total sum of Kinetic and Potential energies. Kinetic energy is the energy possessed by an object because of its movement. Potential energy on the other hand is that energy which is stored by an object as a result of its position. There are two types of potential energy, elastic and gravitational and the one present in a swing and pendulum is gravitational potential energy. Its presence is because neither of them has a spring to produce elastic potential energy and they both work in accordance with the laws ...

Introduction

A wind turbine is a device that uses the kinetic energy derived from wind to create mechanical energy. This simply means the wind’s force pushes the blade into motion. Different wind turbines have different ways of extracting wind energy like most machines. Aerodynamics, on the other hand, simply refers to the flow of air about a body. This makes aerodynamics to be a critical aspect of wind turbines as this flow of air about the turbines is what determines its power output. This paper focuses on the aerodynamic behavior of wind turbines (Hansen 21).
Calculation of forces acting on a body ...

Law of Conservation

The law of conservation describes the way that energy is not lost or created but cycled through the energy system. That means that energy moves in a closed system unless energy is added or subtracted. Even though energy moves through a closed system it can be converted from one type of energy into a different type of energy. Kinetic energy is the amount of energy minus the potential energy. When a car sits at the top of a hill there is potential energy present, when the car gets shoved down the hill that is kinetic energy. Both geothermal and coal can ...

Enzymes are sometimes referred to as biochemistry workhorses because they are utilized by many scientists to speed up a number of chemical reactions. Enzymes are proteins that speed up, or in other words catalyze, specific biological and chemical reactions by increasing the rates of reaction by more than a million factors. An example of these enzymes is Pectinase, which is the enzyme that catalyzes pectin breakdown. Pectin is a part of the cell wall of fruits like tomatoes, mangoes, oranges and apples. Pectins are large colloidal molecules and they are responsible for holding or determining the amount of dispersed particles in extracted ...

Calibration Processes

The preliminary step for the experiment is to perform the calibration of the equipment. The treadmill velocity should be calibrated by marking a point and noting the time it takes to complete a predetermined number of revolutions. This time is used to calculate the velocity by using the length of the belt, which should also be measured. These calibrations should be performed at different ...

Introduction

The activities that take place in a living organism are mainly controlled through the use of enzymes. Enzyme refers to a molecule that is protein in nature and functions as a catalyst to speed up the rate of a given reaction. An enzyme as a protein molecule has three main characteristics. First, an enzyme has its basic function is as to increase the reaction rate and this makes most of the cellular reactions occur more than million times that they would have if the enzyme was absent. Second, almost all enzymes act in a specific manner with only one substrate in order to produce the ...
