CHAPTER 1 INTRODUCTION 1.1 Background The interdisciplinary science that deals with the study of mechanical waves in gases, liquids, and solids is defined as Acoustics. These waves are oscillatory perturbations which move from a source and propagate through the medium of either gas, liquid or solid. The frequency of these oscillations ranges from 20 to […]
There are many types of elevators like hydraulic elevator, Pneumatic vacuum elevator, mine shaft elevator etc. Freight elevator is an elevator which carries freight. “A freight elevator is used to do just what its name implies: to elevate, or lift, freight, or goods. It is built to carry goods rather than people”. “The smallest freight elevators are often […]

Get startedThe Motion of a Mass Spring System The example of a mass attached to the end of a spring is a powerful tool in physics due to the fact that it is analogous to many physical phenomena. To be able to use this example to elegantly describe other more complex systems it is crucial to […]
Refraction Refraction refers to the bending of the transmitted light at the interface between two transparent materials. The angle of refraction depends on the angle of incidence and the relative speeds of the light in the two different media and can be found from the relationship [pic] From this equation we see that the direction […]
Doppler Effect The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) […]
1. Introduction When we say equilibrium, it is a state of balance. It is a condition where there is no change in the state of motion of a body. Equilibrium also may be at rest or moving within a constant velocity. A simple mechanical body is said to be in equilibrium if no part of […]
Christian Hernandez January 25, 2010 Physics Mr. Savage The motion of an airplane or helicopter through the air can be explained and distinguished by physical principals discovered over three centuries ago by Sir Isaac Newton, who worked in many areas of mathematics and physics. Throughout recent science history, three of the most important theories proven […]
The forces going with or against a baseball change the way that baseball is played and change the design of a baseball. Drag can be described as the wind or air resistance against an object. There are 2 types of drag: pressure drag and skin friction drag. Both forces could be working on a baseball […]
Rationale Volleyball is one of my favorite sports that I play although I only play two and that was the reason I decided to focus my mathematical exploration on this simple topic. When told I had to do this exploration, I instantly started searching for topics and/or things I could do but nothing interested me. […]
There is physics all around people in their everyday lives. People do not think about the many ways physics influences them. Physics can be found anywhere including in sports, and soccer has a lot of physics that are very crucial to the sport. The laws of physics, including physics on a soccer player, ball, and […]
In Albert Einstein’s theory of special relativity, he investigated and discovered how light’s speed was not dependent on its observer’ movement or motion. Einstein concluded that because space and time work as a solo continuum (based on the idea that inside a vacuum, regardless of an observer’s speed, light’s speed remains constant), physics’ fundamental properties […]
Albert Einstein is a German-Born American Physicist and philosopher who is generally acknowledged as the preeminent scientist of the twentieth century who challenged and disproved fundamental ideas concerning the physical universe. His theories changed the way physicists think about the universe, treating energy and matter as interchangeable and linking space with time and gravitation. His […]
Sir Isaac Newton is deemed one of the most influential, preeminent scientists in history. He contributed to many different aspects of science throughout his successful life, and made an impact that will last forever. Newton was brought into the world on December 25, 1642 in Woolsthorpe, England. He was born prematurely, and was very ill […]
Sir Isaac Newton was born on January 4, 1643 in Lincolnshire, England. He was a famous English Physicist and Mathematician. He made many contributions in the areas of physics, mathematics, astronomy, and science during the period of the Scientific Revolution. His greatest contribution and what he is known best for would be Newton’s Laws. The […]
Also known as Sir Isaac Newton, Isaac Newton was born on January 4, 1643, in Woolsthorpe, Lincolnshire, England. Newton was an only son of a farmer named Isaac Newton. However, his father had passed away three months before the birth of Newton and it was said that he was not supposed to live. During this […]
Many people have heard of at least the name of Isaac Newton alone. Do people really know his sufficient? Often, he is just thought of as another inventor or creator, but he is much more than that. He played a huge part in what we know of our world today. Isaac Newton was born January […]
Isaac Newton was born in the United Kingdom in 1643. His mother, a widow, soon remarried and Isaac did not like his new step father. He attended school where he did well and then attended to Trinity College, Cambridge. Here he thrived, but his most fascinating work was done away from school. Trinity College closed […]
Isaac Newton should be considered as the most influential person in history, because of his many contributions to our world today. His largest field of accomplishment was in math. Growing up as an abandoned child, Newton found his way to becoming the most successful scientist in the world. He was an English mathematician, astronomer, theologian, […]
