... We can see that the inertial systems are oriented from each other by a four-dimensional rotation. The homogeneous Lorentz transformation just specifies this rotation relative to a fixed inertial system as reference frame. This transformation in general can be decomposed into a pure Lorentz transform ...

... It can be seen that for δ < 0, the Ey component trails the Ex component in time. The electric field thus moves from the x to the y direction, or in the right-hand direction with respect to k. In the opposite case, for δ > 0 the Ey component leads the Ex component, so the electric field moves in the ...

... Conceptual Example 21-10: Charge at the center of a ring. Imagine a small positive charge placed at the center of a nonconducting ring carrying a uniformly distributed negative charge. Is the positive charge in equilibrium if it is displaced slightly from the center along the axis of the ring, and i ...

... Recall that in our mechanical systems, work was determined using the equation below where r is the distance an object is moved. From unit 13 we learned that the force on a charged particle in an electric field is given by the following equation. As a result, the work done in moving a charge fr ...

... Total Momentum of a System of Objects • A “System” is an object or a collection of objects. • The Total Momentum of a system equals the vector sum of the momenta of all the objects in the system: • PTotal System = P1 + P2 (for a system of two objects) • Also called the “Net Momentum”: PNET or PTOT ...

... 3. A point mass m under no external forces is attached to a weightless cord fixed to a cylinder of radius R. Initially the cord is completely wound up so that the mass touches the cylinder. At time t = 0, a radially-directed impulse is given to the mass so that it’s initial velocity is v0 , and the ...
