Relative Motion on Superphysics

Motion from A to B

Sun, 08 Sep 2024 00:00:00 +0000

EVERYTHING that is moving must be moved by something.

It does not have the source of its motion in itself.

If the source of its motion in itself, let AB be taken to represent that which is in motion essentially of itself and not in virtue of the fact that something belonging to it is in motion.

What is Locomotion?

That which is the first movement of a thing-in the sense that it supplies not ‘that for the sake of which’ but the source of the motion-is always together with that which is moved by it by ‘together’ I mean that there is nothing intermediate between them).

Acquired states are not alterations.

Everything that undergoes alteration is altered by sensible causes, and there is alteration only in things that are said to be essentially affected by sensible things.

The truth of this is to be seen from the following considerations. Of all other things it would be most natural to suppose that there is alteration in figures and shapes, and in acquired states and in the processes of acquiring and losing these: but as a matter of fact in neither of these two classes of things is there alteration.

Is every motion commensurable with others?

Is every motion commensurable with every other or not?

If they are all commensurable and if two things to have the same velocity must accomplish an equal motion in an equal time, then we may have a circumference equal to a straight line, or, of course, the one may be greater or less than the other.

The Cause of Change

Since wherever there is a movent, its motion always acts upon something, is always in something, and always extends to something (by ‘is always in something’ I mean that it occupies a time:
