... Now let us examine this measurement from the point of view of the observer on the Earth. From her point of view, the length of spaceship A is smaller than L0 . And the moving stopwatches slow down compared to watches left on the Earth, so the time measured by the watches on the Earth is longer than ...

Newton`s Laws
... Electrical forces are an attractive or repulsive force between electrically charged objects. If the objects have opposite charges, they are attracted to each other. If they are the same, they are repulsive . Electrical forces are very similar to magnetic forces, but at still fundamentally different. ...
