... translation with velocity v along the axis of x in the direction of increasing x is then imparted to the rod. We now inquire as to the length of the moving rod, and imagine its length to be ascertained by the following two operations:— (a) The observer moves together with the given measuring-rod and ...

... Doppler effects For a source moving with a speed very much smaller than the speed of light, the shift in frequency between source and observer is given by: fO = fS (1 ± vrel c ) fO : frequency observed by the observer. fS : frequency emitted by the source. vrel : speed of the source and observer re ...

... this is the action-at-a-distance concept. An alternative approach is the field concept where one charge sets up an electrostatic field at each point in space and the second particle feels a force due to the field. These two points of view may seem to be equivalent and so the introduction of the fiel ...

... The force on the electron = qE = 1.6x10-19 x 6.33x108 = 1.01x10-10 N Because the electron is negative, the direction is opposite to the field's direction (away from the negative charge and towards the positive charge). It will feel a force to the right. Since F=ma, a = F/m a = 1.01x10-10 / (9.11x10- ...
