First question, we are looking at the various prepositions given by aristotle in the past.
00:08
So we want to show that the equation p delta t is equals to bwd satisfies all the prepositions that were given by aristotle.
00:22
So the first proposition is that for an equal power right right for a power that is equal to p and we have a time interval delta t you will move an object of omega 2 omega 2 by a distance of 2d so if you are to substitute in omega to be omega over 2 now this implies that because b is a constant in order for our new d to satisfy the previous equation, that must be equals to bwd, then our d prime over here must be equals to 2d.
01:35
For the second prepositions, says that it will move omega over 2, a distance of d if our time interval is halved.
01:49
So suppose our time interval is halfed, to become half of b wd and therefore putting that into the omega say that it will move an object of omega over 2 distance of d.
02:16
For the third statement we are looking at if the load w is moved a distance d2 in time interval or t over 2 which implies basically expression then a power that is half of this value, p over 2, will move omega 2 by a distance of d in the time interval delta t so this would be equals to half of p times delta t can substitute p times delta t to be b wd which implies that we are moving in omega 2 object by distance d.

So it shows that all of the statements given by aristotle actually applies to our equation over here.
03:50
And we want to fit in a particular case or particular example in which this aristotle's theory actually fits...
