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

The purpose of this lab was to learn about Newton’s laws of motion by completing an experiment‚ to see how the forces act on objects. The independent variable of this experiment is the type and amount of materials used for the interior of the vehicle (out of the material list) and how they were used. The dependent variable is how and if the interior of the vehicle protected the egg from getting cracked. The controlled variables of this experiment were the height that the vehicle was dropped from

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

Pre-lab: Newtons Three Laws of Motion: There are three laws of motion that have been stated by Sir Isaac Newton during the sixteenth century that are looked upon even today. The first of these laws states that an object will stay in at rest or in a constant velocity unless a force acts upon it. In simplest terms this means that if u place an apple on the table it isn’t just going to roll off. The second of these laws states that when a force acts upon an object it causes it to accelerate

The Second law of thermodynamics There are four laws of thermodynamics‚ which define temperature‚ energy and entropy‚ characterizing thermodynamic systems. To understand the second law of thermodynamics we should know that on a basic level it explains the “catch twenty-twos” to the first law of thermodynamics. The first law of thermodynamics says that energy can never be created nor destroyed‚ only transferred to another form of energy. The second law states that some processes do not take place

How does the mass of a ball affect the distance it will travel ? Exploring Newtons 2nd Law of motion. Background Research How does changing the mass of an object effect how far it will travel ? This question can be answered by Newtons 2nd law of motion; Force equals mass multiplied acceleration (F= ma). This law states that a force on an object will cause it to accelerate in the direction of the force. The greater the force exerted on the object‚ the greater the acceleration. But how does

: As you can see that the greater the amount of pennies were added at the top of the cup‚ the shorter the distance of the cup moved and it included all of the three Newton’s laws. My hypothesis actually turned out to be accurate. It’s really fascinating that how only 1 experiment can prove all of Newton’s three laws of motion just like that. When the marble was getting released from the ramp I observed it hitting the cup and surprisingly the cup didn’t fall off or changed directions it went in

Preparation of SKEO The extraction of S. khuzistanica was performed by hydro distillation and clevenger apparatus for 5 hours. Once extraction was completed‚ the resulted essential oil was dehydrated using sodium sulfate (Merck). The essential oil was stored at temperature of 4ºC until using (12). In order to provide different concentrations of the extract‚ Dimethyl sulfoxide (DMSO) was used. Gas chromatography/mass spectrometry analysis of essential oil Isolation and measurement of the sample
