Dr. Harold Williams. Reading Quiz . The photoelectric effect tells us that. electrons have a wave nature.. light has a particle nature.. a photon can be converted into an electron.. . In classical mechanics, the momentum of a particle is defined as a product of its mass and its velocity, . . In an isolated system of particles, with no net force acting on the system, the total momentum of the system remains the same. However , we can see from a simple though experiment that the quantity . Activity 1:. What do you see?. What questions would you like answered about this picture?. What is . particle physics. ?. Particle physics is the study of the fundamental . building blocks of nature and the forces they exert on each other. RAF211 - CZJ1 What was Angular Momentum Again?. If a particle is confined to going around a sphere:. At any instant the particle is on a particular circle. r. v. The particle is some distance from the origin, . r. Mass energy equivalence. In quantum mechanics , we considered that kinetic energy could be increased only increasing by its velocity. But now dealing with relativistic mechanics we take mass variation into account.

In a linear system, the linear responses of linear independent sources can be combined in a linear manner.. This allows us to solve circuits with one independent source at a time and then combine the solutions.. Thomas Vidick. California Institute of Technology. . Joint work with . Itai Arad (Technion),.
