something he or she would not otherwise do” Work-Energy PrincipleThe change in the kinetic energy of an object is equal to the net work done on the object.This fact is referred to as the Work-Energy Principle and is often a very useful tool in mechanics problem solving. It is derivable from conservation of energy and the application of the relationships for work and energy‚ so it is not independent of the conservation laws. It is in fact a specific application of conservation of energy. However

Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher. He was an astronomer‚ merchant and mathematician‚ and after

Born in Vienna on February 20‚ 1844. He was an Austrian physicist and philosopher whose greatest achievement was in the development of statistical mechanics‚ which explains and predicts how the properties of atoms (such as mass‚ charge‚ and structure) determine the physical properties of matter (such as viscosity‚ thermal conductivity‚ and diffusion). His father‚ Ludwig Georg Boltzmann‚ was a tax official. But his father died when he was 15 yrs. old. Boltzmann studied physics at the University

In 1981 a physicist working in the field of quantum mechanics realized that classical computing could not efficiently simulate quantum mechanical systems. The scientist was Richard Feynmen and he proposed the

In 1932 he won the Nobel Prize in Physics for his work in Quantum Mechanics. With the Nazi’s in power‚ and World War two on the horizon it was inevitable that his German heritage would play a crucial role in his career. Before Germany’s blitzkrieg on Poland Heisenberg decided to make one final visit of his friends in the

Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has

contributions to the behavior of fluid in an enclosed space have been an invaluable and important concept in fluid mechanics and its applications especially in the automotive industry‚ mechanical engineering‚ and hydraulics. Pascal’s law or the principle of transmission of fluid-pressure that was proposed by Blaise Pascal. According to Bloomfield‚ the law is a principle in fluid mechanics that states that for a particular position within a fluid at rest‚ the pressure is the same in all directions. Pascal’s
