... t=t’ Situations: 1. If both source and test charges are at rest, the force pairs no doubt obey Coulomb’s Law. 2. If the source charge suddenly starts moving, as shown by arrow. In response, the force vector on the test charge must pivot to follow the source charge. Does this happen ? Or is t ...

... speed. Consider a point on flywheel rim, at distance R from the axis of rotation. If the flywheel speeds up from initial angular speed ω1 to angular speed ω2 in time t, then the speed of the point increases from speed u = ω1 R to speed v = ω2 R in time t. By using acceleration, a = (v-u)/t, the line ...
