... Negatively charged particles are emitted from the negative electrode (cathode). These “cathode rays” are accelerated toward and through the positive electrode (anode) and smash against the far end of the tube. They leave tracks by the light emitted by the residual gas along their path. The electrons ...

4.3 Newton`s Second Law of Motion
... 4.2 Inertia and Newton’s First Law of Motion According to Aristotle, the natural state of objects was to be at rest, and if you got them moving, eventually they would come to rest again. Galileo did experiments rolling balls down and up inclined planes, and realized that, in the absence of some kin ...
