Radiation of Fast Charged Particles in Media?
... Passing through many boundaries a charged particle generates TR (including possible VCR) at every single one of them. The observed radiation is the final result of interference. Every secondary wave (see Introduction) emitted from a certain point of particle trajectory has its own phase. If the phas ...

... Magnitude of torque is defined as the product of the force exerted on the object to rotate it and the moment arm. When there are more than one force being exerted on certain points of the object, one can sum up the torque generated by each force vectorially. The convention for sign of the torque is ...

... Instantaneous velocity, like average velocity, is a vector quantity. Equation (2-3) define its x-component, which can be positive or negative. In straight-line motion, all other components of instantaneous velocity are zero, and in this case we will often call v simply the instantaneous velocity. T ...

... The Sign of a Torque • Torque is a vector quantity. In this textbook, we will assign each torque a positive or negative sign, depending on the direction the force tends to rotate an object. • We will use the convention that the sign of the torque is positive if the rotation is counterclockwise and n ...

... The graph below shows how the momentum of car A changes with time just before and just after a head-on collision with car B. Car A has a mass of 1 500 kg, while the mass of car B is 900 kg. Car B was travelling at a constant velocity of 15 m∙s-1 west before the collision. Take east as positive and c ...
