Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total

Hardy-Weinberg Equilibrium One of the most difficult concepts to understand about the process of evolution is how changes in the genetic composition of a population affect the phenotypic composition of a population‚ and how both ultimately act to allow evolution of the species. Charles Darwin’s theory of evolution emphasizes that populations‚ not individuals‚ evolve. The purpose of my experiment was to test the allele and genotype frequencies. Alleles for a gene are represented by letters of

egrettably‚ Professor Jayavel Sounderpandian passed away before the revision of the text commenced. He had been a consistent champion of the book‚ first as a loyal user and later as a productive co-author. His many contributions and contagious enthusiasm will be sorely missed. In the seventh edition of Complete Business Statistics‚ we focus on many improvements in the text‚ driven largely by recommendations from dedicated users and others who teach business statistics. In their reviews‚ these

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer

Dc circuits and Ohm’s law of measurments Helina Wolfe Tannaz Farnoudi and Najah Rouse Physics 246-205 Professor Joe Renaud 09/23/13 Word count:1453 Abstract: The aim of this experiment was to understand the relationship between the variables of Ohm’s law and how they are part of an operation of an electric circuit. Introduction: This experiment was done in two parts. The first part consisted of understanding how to determine the current‚ voltage and resistance

Static Electricity Everything is made up of tiny particles called atoms. The atoms are made up of even smaller parts called protons‚ electrons and neutrons. Protons have a positive charge (+)‚ electrons have a negative charge (-) and neutrons have no charge at all‚ they are neutral. Atoms normally have the same amount of electrons and protons‚ making them neutral and having no charge. When rubbing things together‚ electrons can move from one atom to another‚ resulting in some atoms having extra

Rotational Falls in Horses By Veronica Spaulding What is a rotational fall‚ and what can we do to prevent them? There has been a lot of discussion among the eventing community about how to prevent rotational falls — a fall where the horse hits a fence with its front legs or chest and its body somersaults over the fence‚ with the fence acting as a pivot point. In such tragedies‚ the rider is thrown out of the saddle and flies over the jump before the horse. In a worst case scenario‚ the horse

Lab II‚ Problem 3: Projectile Motion and Velocity Oct. 06‚ 2013 Physics 1301W‚ Professor: Hanany‚ TA: Vladimir Abstract A ball is tossed obliquely. The vectors of position and velocity are measured. The acceleration is calculated. Introduction A toy company is now making an instructional videotape on how to predict the position. Therefore‚ in order to make the prediction accurate‚ how the horizontal and vertical components of a ball’s position as it flies through the air should

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this
