Then, we will divide the speed of the moving point by that length. In this way, the time it will take for the object (moving at a constant speed of [b]1/L[/b]) to complete the path will be proportional to its length. This is what we have done in this activity showing the definition of a radian.[br][br]We can observe that the accuracy leaves much to be desired, even though both points are moving at a constant speed.
