Therefore the sum of all the energies in the system is a constant. TMEinitial=TMEfinal 3. Explain the basic ideas that govern the design and operation of a roller coaster. A roller coaster is operated and designed through the application of Physics. The law of Conservation of Energy governs the changes in a coaster ’s speed and height. Simply put‚ the higher an object is off the ground‚ the more potential energy it has - that is‚ potential to gain speed as it falls. As it falls toward the ground

1.1 GRAVITY AND GRAVITATIONAL FIELDS 1.1.1 Define weight as the force on an object due to a gravitational field. Weight is the force experienced by an object due to the presence of a gravitational field. This force is directly related to the strength of the gravitational field acting on an object and the mass of that object. m = mass‚ g = acceleration due to gravity m = mass‚ g = acceleration due to gravity Fg = mg Fg = mg 1.1.2 Explain that a change in gravitational

Aristotle (Greek: Ἀριστοτέλης [aristotélɛːs]‚ Aristotélēs) (384 BC – 322 BC)[1] was a Greek philosopher and polymath‚ a student of Plato and teacher of Alexander the Great. His writings cover many subjects‚ including physics‚ metaphysics‚ poetry‚ theater‚ music‚logic‚ rhetoric‚ linguistics‚ politics‚ government‚ ethics‚ biology‚ and zoology. Together with Plato and Socrates (Plato’s teacher)‚ Aristotle is one of the most important founding figures in Western philosophy

Application Of Physics In Medicine Medical physics is generally speaking the application of physics concepts‚ theories and methods to medicine. A medical physics department may be based in either a hospital or a university. Clinical medical physicists are often found in Diagnostic and Interventional Radiology‚ Nuclear Medicine and Radiation Oncology. However‚ areas of specialty are widely varied in scope and breadth e.g.‚ clinical physiology‚ neurophysiology (Finland)‚ and audiology

LIGHT DEPENDENT RESISTANCE INTRODUCTION In the society‚ some times street lights glow in day time due to any reason. In mines area people face many difficulties due to absence of light in the nights. In frontier and hilly areas‚ people face many problems due to damaged street lights. For solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity

The following is a project made by anonymous: INTRODUCTION The general purpose photoconductive cell is also known as LDR – light dependent resistor. It is a type of semiconductor and its conductivity changes with proportional change in the intensity of light. There are two common types of materials used to manufacture the photoconductive cells. They are Cadmium Sulphide (CdS) and Cadmium Selenide (CdSe). Extrinsic devices have impurities added‚ which have a ground state energy closer to the conduction
