PPT-The new invariants Energy and momentum in relativity

Electric and Magnetic fields What does mass mean QUIZ at 120 4dimensional physics The principle of relativity requires that if the laws of physics are to be the same in every inertial reference frame the quantities on both sides of an sign must undergo the same Lorentz transformation so they stay equal . . 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 . 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. Galilean Transformations. x’. y’. P. v. x. y. x = x’ + vt. x’ = x - vt. Divide equations by t. u = u’ + v. u’ = u - v. u’. Example:. A train travels through a station at a constant speed of 8.0ms. Randy Wayne. Plant Biology Retreat, August 25, 2012.
