Motion Path animations determine the route (path) and the direction in which the animated slide object moves across or around on the slide. When you add a motion path animation to an object, you see the path as a dotted line with two arrow-heads. PowerPoint 2016 sports a faded preview of the animated slide object at the end point of the motion path.
