Is gravity always 9.8m/s2?? INTRODUCTION: A simple pendulum consists of a mass m swinging back and forth along a circular arc at the end of a string of negligible mass. A pendulum is a weight suspended from a pivot so that it can swing freely. Gravity is the pull that two bodies of mass exert on one another. There are several simple experiments that will allow you to calculate the acceleration due to gravity of a falling object. A simple pendulum can determine this acceleration. The only variables

Aim What is the effect of differing pendulum length on its period? Hypothesis If the length of the pendulum is decreased‚ the period will decrease. Variables Independent: The length of the pendulum (cm) Dependent: The period of the pendulum (s) Controlled: The weight of the swinging mass The angle for maximum displacement Materials: Pendulum (can be as simple as a mass tied to string attached to a piece of cardboard) Retort stand and clamp Stopwatch Ruler Protractor Masking tape

the time period of a pendulum Aim: To investigate the factors affecting the time period of a pendulum. Introduction: The time period of a pendulum is the time taken for the pendulum to swing from the first position‚ A‚ through positions B and C and back to position A again. [pic] Many factors can affect the time period of the pendulum. These factors are: length of string‚ angle from which the pendulum is dropped‚ the air resistance and the weight of the pendulum. In this experiment I

Word Processed Practical Report Pendulum Aim: To investigate the relationship between the length of pendulum and the time it takes. Theory: Hence the gravitational acceleration “g” can be calculated by this equation: T=2πLg T=2πLg (T the period in seconds‚ l the length in meter and g the gravitational acceleration in m/s2) Method: As stated earlier in the introduction‚ it was decided to measure the time for 10 complete swings‚ in order to reduce

In the excerpt‚ “My Name” from Sandra Cisneros’ novel‚ “The House on Mango Street”‚ she uses specific diction‚ syntax‚ and imagery to create tone. The best example of this is in paragraph 3 when Esperanza talks about her grandmother. Using imagery for example‚ Cisneros paints a picture by saying‚ “My great-grandmother. I would’ve liked to have known her‚ a wild horse of a woman‚ so wild she wouldn’t marry. Until my great-grandfather threw a sack over her head and carried her off. Just like that

Misconceptions about Pit Bull Terriers CM 220 Sean Jolley May 16‚ 2013 Kaplan University It is better to understand the breed and where they come from before making assumptions about the type of animal they are. The Europeans wanted a stout muscular breed that had feistiness to it that they could use for baiting or rat fights (pitbull411.com). Yes‚ it is true that the breed started off as a fighting dog that was used to bait bulls that were uncontrollable by their owners. But when Europeans

Introduction: Over the past half-century‚ the reputation of pit bulls has grown gradually worse. The breed that once represented America’s dedication and determination on recruitment advertisements is now “a status symbol in drug and gang culture” (Reed‚ 2008). This trend can be traced back to the 1980s when dog-fighting attracted widespread media publicity. Since then‚ reports of pit bull attacks has significantly increased‚ and these breeds are labeled as vicious killers‚ restricted by the society’s

Year of Magical Thinking: Syntax and Synthesis Syntax: Joan Didion uses many syntax devices to emphasize the important emotions or tones she is trying to create. One device that she uses throughout the book is parenthetical aside. On page 5 and several other places she writes “And then—gone” (Didion 5). One of the struggles Didion faces is the fact that her husband is actually gone and how it was so unexpected. The parenthesis aside created the dramatic effect showing how everything was as expected
