As two successive positions of it contain the second side of the polygon above
mentioned , it is evident that the osculating plane passes from one position to the
next by revolving about the tangent to the curve . 13. Thus , as we proceed along

all the sides being produced each in the direction in which the moving point
describes it while passing round the figure . This is true whether the polygon be
closed or not . If closed , then , as long as it is not crossed , this sum is four right
angles ...

( c ) If the components of the velocity parallel to each axis be equimultiples of the
distances from the other axis , the path is a straight line passing through the
origin . ( d ) When the velocity is uniform , but in a direction revolving uniformly in

When the acceleration is directed to a fixed point , the path is in a plane passing
through that point ; and in this plane the areas traced out by the radius - vector
are proportional to the times employed . This includes the case of a satellite or ...
