This site has got games, movies, jokes, songs, pictures, illusions and some odd trivia - what else could you possibly want? If you're suitably inclined a load of techie stuff as well.
Motion: A body will rigidly maintain its state of uniform motion in a straight line, or its state of rest, unless it is acted upon by an impressed force. The alteration of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. To every action, there is an equal and opposite reaction. |
