In that case, its velocity must have been zero; also, it will end up in the same place where it started.
its magnitude is greater thatn the distance travelled by the object
The amount of work done on the object is (force) multiplied by (distance) = (25) x (0) = zero .
When an object moves from point A to point B , its displacement is the straight line distance between those points. So, by definition, it is the shortest possible path. The object can certainly travel by a curved path from A to B so its actual distance traveled would be longer then its displacement. This would be true regardless of how much time it takes to travel the paths.
it must be smooth
True . A+

Its simply called "Distance"
Yes. You can also find speed by distance divided by height
it must be smooth
Total distance (dtotal) traveled divided by the time (ttotal) it took to do that equals the average speed (savg) for the journey. It might be written like this:dtotal / ttotal = savg
If an object accelerates, there must be a force acting on it according to newton's second law, so I would answer true.
