Movement and Rest on Superphysics

The Start of Motion

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

Was there ever a becoming of motion before which it had no being, and is it perishing again so as to leave nothing in motion?

Or are we to say that it never had any becoming and is not perishing, but always was and always will be?

Motion from Nowhere

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

Motion may exist though at one time it had not existed at all.

From Motion to Rest

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

Why are some things in motion and at another are at rest again?

1 of 3 things must be true:

All things are always at rest
All things are always in motion
Some things are in motion and others at rest

The things in motion are always in motion
The things at rest are always at rest, or
They are capable alike of motion and of rest

Some things in the world are always motionless, others always in motion, while others again admit of both conditions.

The Causes of Motion

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

Now of things that cause motion or suffer motion, to some the motion is accidental, to others essential:

thus it is accidental to what merely belongs to or contains as a part a thing that causes motion or suffers motion,

The Source of Movement

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

Movement may come about in either of two ways.

Either the movement is not itself responsible for the motion, which is to be referred to something else which moves the movent, or the movent is itself responsible for the motion.

The Source of Movement

Still more unreasonable is the consequence involved that, since everything that is moved is moved by something that is itself moved by something else, everything that has a capacity for causing motion has as such a corresponding capacity for being moved: i.e. it will have a capacity for being moved in the sense in which one might say that everything that has a capacity for making healthy, and exercises that capacity, has as such a capacity for being made healthy, and that which has a capacity for building has as such a capacity for being built.

Motion is Eternal

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

There must always be motion without intermission. This means that there must necessarily be something (either one thing or many) that first imparts motion).

This first movement must be unmoved.

Locomotion is the primary motion

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

Is it possible to have a continuous motion?

If there is, what is its primary motion?

Rotatory motion

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

Rotatory motion is an infinite motion that is single and continuous.

The motion of everything that is in process of locomotion is either:

rotatory
rectilinear or
a compound of the two

Consequently, if one of the former two is not continuous, that which is composed of them both cannot be continuous either.

Does Turning Back Involve a Stop?

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

Suppose the line E is equal to the line Z. A proceeds in continuous locomotion from the extreme point of E to G. When A is at B, D is proceeding in uniform locomotion and with the same velocity as A from the extremity of Z to H.

Time cannot be divisible into Time-atoms

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

Let us suppose a time ABG and a thing D.

D is white in the time A and not-white in the time B.

Then D is white and not-white at the moment G.

Rectilinear motion versus Rotary

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

Rotation is the primary locomotion.

Every locomotion is either rotatory or rectilinear or a compound of the two.

The two former must be prior to the last, since they are the elements of which the latter consists.

The Nature of the First Movement

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

The first movement must be without parts and without magnitude.

This is based on the following premises:

Nothing finite can cause motion during an infinite time.

We have 3 things:
