Quantum mechanics

Physics plays an important role in the mechanics of a roller coaster. The thrilling ride cannot be appreciated, if the physics of a roller coaster is not understood. The loops, bends and hills are all affected by physics. The first hill of a roller coaster is the initial start of energy. Potential energy begins the transfer of energy on the first hill. A chain motor pulls the cars to the top of the hill creating potential energy. Potential energy being defined as the energy determined by its…

Dirt bike or motocross racing is an extremely competitive sport that has been enjoyed by masses of people across the globe. Millions of people have either watched or are very passionate about dirt bike racing. This is a sport that has been around for over one hundred years when the idea first came about in the U.K. motorcycle trial competitions in the early 1900’s ("Motocross"). As the sport grew in popularity, many improvements were made including: the terrain of the tracks, motorcycle…

Greek scientists Archimedes. His theory is now referred to as Archimedes 's principle, or the law of fluid mechanics. It implies that there is force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. He hypothesized this theory while in the bath. Unfortunately his theory only covered fluid mechanics and didn’t elaborate completely on force. However he was one of the first scientists to discover…

Breaks are not something people take the time to think about. Even if they are fundamental to the vehicles many people use every day. The functionality of breaks is contributed to physics and engineers ability to understand that physics. There is a lot going on when people press on the brake pedal in their car. The most basic principle of brake pads is in fact friction. This friction is the thing that transfers the energy of the car moving forward to heat energy. Brakes also use pressure as a…

IV: Rebuttals to my Characterisation of Reclamation In the above, I have created a model to represent to sociological phenomena of the reclamation of slurs. I have given an example how we can see this mechanism at work with respect to the word queer. Though this provides evidence in support of my thesis the question arises as to what measure should be used to more so test the effectiveness of the model. What should be considered and how can my thesis best be supported? The model which I have…

Parana Pine: For the Parana Pine I obtained the published value from a website since the values on the lab sheet didn’t have a values for Parana Pine. Firstly, I calculated my own Young’s Modulus Value with the result got from the tests using the equation for Young’s Modulus in Bending: E= l³/(4bd^3 ) x ( Δw)/( Δx) From using this equation, I achieved 14.44 E/GPa as a value, the published value, was: 11.37 E/GPa found on ‘The Wood Database’. The difference between my results and the…

Fig. 5 shows the monotonic and cyclic stress-strain responses of selected specimens having all influential parameters considered in this study, such as the volumetric ratio of transverse steel reinforcement, number of CFRP layers, and aspect ratio. In this figure, the axial stress was calculated by dividing the axial load to the column cross-sectional area, and the corresponding axial strain was derived from the average readings of the four LVDTs divided by the central gauge length of each…

Explain how Newton 's first law applies to air bags, seat belts, and headrests. Newton’s first law applies to air bags, seat belts, and headrests in terms of keeping your body at rest while you are driving, which in turn will keep you safe. When you crash your car, the motion of your body in the car matches the motion of the century itself, so when it crashes, your body has the tendency to stay in motion. So, with the headrest, seatbelt, and airbag, they are all designed to slow down the forward…

Three tests are done through a Gizmo to determine how radius, mass, and velocity affects centripetal acceleration of an object undergoing uniform motion. The results show centripetal acceleration is affected by radius and velocity but not mass. It gives a better understanding to why objects in uniform motion accelerate towards the centre of a circle. Introduction The purpose of this lab is to determine how the radius, mass and speed of an object can affect the centripetal acceleration of the…

A world leading physicist, astronomer, natural philosopher, alchemist, theologian and mathematician, Sir Isaac Newton is known globally for being one of the most influential men to ever live. Newton was born on Christmas day, 1642 in Woolsthrope-by-Colsterworth, United Kingdom where his grandparents raised him. In the beginning Isaac was heavily pressured into being a farmer, however he was so terrible at farming they decided to send him to university. At 19 Isaac attended his first classes at…
