2. Equations of motion respect relativity if the action is relativistically invariant. Sup pose that the action can be written as S-JdtL and L-J aC, where L is the Lagrangian density. In tis exercise, you will verify that S is a Lorentz scalar if C is a Lorentz scalar. To do this, you want to verify that d'rd d2d is nvari- ant under Lorentz transformations. To do that, recall from your calculus class how, under changes of variables, the integration...
In the theory of relativity, the mass of a particle with velocity v ism=mo/(square root ((1- v^ 2)/ c^2))where mo is the mass of the particle at rest and ci s the speed of light. What happens as v goes to c?
general relativity question. Instructions The first problem is just a test of how well one knows the methods of averaging over directions. This is a standard tool which is used in many areas of classical electrodynamics and general relativity. e.g, in the context of the radiation problem and in the context of particle motion in inhomogeneous electromagnetic fields. The second problem is just a test of how well one understood the content of the present lecture. Solve the problems and...
