Webmatically describe various laws of force and motion. There were just a few niggling problems that were not yet understood. One of those prob-lems was the photoelectric effect. In 1905, scien-tists had observed this effect, but no one could explain it. It seemed to contradict the Newtonian laws of motion. Another area of controversy was WebNov 5, 2013 · And they remained off until Einstein, and general relativity, explained why Mercury moves the way it does.
