Purpose: To determine the most powerful group in carrying someone upstairs. Background Information: A force is a push or pull on an object with the effect of the object’s interaction with another object. Forces only exist as a consequence of an interaction. To find the force of an object use the formula: F = m • a. Where F‚ stands for force‚ m stands for mass and a for acceleration. Displacement is how far away the endpoint is from the starting point in a straight line. Work is the means of transferring

Stephen Hawking started his studies at Cambridge University. He began to study cosmology but later then realized that was not the path he wanted to go down. Eventually he became a professor of theoretical physics. By the age of 21‚ Hawking contracted ALS (amyotrophic lateral sclerosis)‚ a neurological disease that is incurable and very fatal. ALS eats your nervous system very slowly. From then until now‚ Hawking has defied this disease and is still alive to this day. Hawking has a family‚ and three

Introduction Isaac newton—English astronomer‚ physicist‚ mathematician‚ and scientist—became interested in science as a boy and even invented several devises while he was still young. He attended Cambridge University and later taught there. In Optics‚ newton published his principles of light and colour‚ and in his mathematical principles of natural philosophy (also known as the principia)‚ he discussed the laws of motion and the theory of gravity. Besides his scientific study‚ he spent much time

Mach believed that observations were above all other methods of discovery and was firmly against theorizing ([3] 86-87). Mach’s philosophy was that “A scientific law was a quantitative relationship between one observable phenomenon and another” ([3] VIII). He thought that since atoms could not observed that they must not exist ([3] 86). Not only were there not observations of atoms‚ but they were also a theory. Although the atomic theory was gaining support‚ Mach would not believe in it because it

Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated‚ Classical mechanics can still be used for many everyday problems with bigger and slower moving objects. However‚ when dealing with extremely fast moving or small subatomic particles a Classical approach will not

My interest in life is going to college and to become a Chemical Engineer. Chemical Engineers is the combination of chemistry‚ math‚ and physics to design and operate the manufacturing processes. I want to major in engineering because ever since I was a child I realized that I am asking myself the same questions‚ how do things work‚ what do they do‚ and how can I do something better about the environment. I have always enjoyed challenging myself mentally‚ construct new things‚ and math is my best

Neptune is one of the most extraordinary events of the century. Growing up‚ Galle attended a Gymnasium located in Wittenberg and from 1830-1833 he continued his studies at Friedrich-Wilhelms-Universitat‚ Berlin. Galle then became a teacher and taught physics and mathematics at the Gymnasium sited in Guben. Later on in life‚ he moved to the Gymnasium in Berlin. In 1835‚ Galle began working at the Berlin observatory as an assistant to Johann Franz Encke. While working at the observatory‚ he made good use

Megamind In the sleepy‚ little town of Woolsthorpe‚ England‚ January 4‚ 1643‚ Hannah Newton became the proud mother of a small baby boy. The boy’s father had died three months prior to his son’s birth. So to honor him‚ Mrs. Newton named her son Isaac in remembrance of his father‚ Isaac Newton Sr. However‚ she never dreamed her son‚ descended from the humble farmer‚ would one day become one of the greatest scientific minds in history. After raising young Isaac for three years‚ Mrs.
