Controlled variables: 1. The lighting was kept constant during the complete test. No additional light sources were added throughout the experiment‚ nor were any light sources removed throughout the experiment. This minimized the errors involved with trying to read and record the indicated measurements on the ticker tape‚ as well as the ability to analyze the experiment. 2. The same person measured and recorded the height and length of the incline plane and level horizontal track to ensure consistency

SIR ISAAC NEWTON; ORAL REPORT. I just planned on saying something like ‘Our report is on Sir Isaac Newton’. In 1643 he was born to a man who didn’t want him so his mother was supposed to take care of him but‚ she wanted to raise a second family with a new husband so she took him to live with his grandparents. He lived there until 1653 when his mother returned. By then he was ten years of age and had already been denied plenty of attention from his mother possibly explaining his complex character

Newton’s Laws First let’s get to know some history about the man behind all of this‚ Sir Isaac Newton. Sir Isaac Newton‚ the man who is responsible for what we all have come to know as the “Laws of Motion” was born on January 4‚ 1643‚ which is very often displayed as December 25‚ 1642‚ if using the older version of the Julien calendar‚ in the Helmet of Woolsthorpe‚ England. Sir Isaac Newton is believed to be one of the most influential scientists known to have ever lived. His ideas became the basis

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

HOMEWORK PROBLEMS Chapter 4: THE LAWS OF MOTION PART-A: Hand in your answers in class on scantron on Wednesday 22 September-2010. The questions have been numbered so you can use the back side of an older scantron. Write your name‚ class (1401) and HW # 4 on the scantron. 1. A horizontal force of 95.0 N is applied to a 60.0-kg crate on a rough‚ level surface. If the crate accelerates at 1.20 m/s2‚ what is the magnitude of the force of kinetic friction acting on the crate? (a) 23.0 N (b) 45.0 N

Tori Suchy Physical Science Honors 1st block October 4‚ 2012 Balloon Powered Car Problem: In order to create a race car that can travel a minimum of eight meters powered by a nine inch balloon. We need incorporate Newton ’s Law of Motion including speed‚ velocity‚ and acceleration. Hypothesis: If a car were to be made out of homemade materials‚ then it would be possible for it to travel 8 meters powered by a nine inch balloon. Independent Variable: building the car from homemade materials

Isaac Newton Isaac Newton was born on December 25‚ 1642‚ in Woolsthorpe‚ England. His father died before he was born‚ and his mother mother‚ Hannah Newton‚ remarried and moved away. She left Newton to be raised by his uncle. In 1654‚ he was sent to the local grammar school‚ then he enrolled at Trinity College‚ at the University of Cambridge‚ in 1661. He received his bachelor of arts in 1665‚ and was named a fellow of the College two years later. In 1666‚ Newton made three of his greatest discoveries

Physics 211 Experiment #4 Newton’s Second Law – Atwood’s Machine Newton’s second law (FNET = ma) can be experimentally tested with an apparatus known as an “Atwood’s Machine” (See Figure 1.) Two weights of unequal mass‚ connected by a thread‚ are draped over a pulley‚ as shown in the figure. When released‚ the larger mass accelerates downward and the smaller one accelerates upward. Figure (1a): The Atwood’s Machine‚ showing the pulley and the two masses after a run. Figure (1b): A close
