Isaac Newton’s three laws of motion and law of gravity apply to space-time, the 3D space (spatiocosm) with 1D time of classical physics. What do these laws look like in time-space, with 3D time (temporocosm) and 1D space?

Newton’s laws of motion in space-time state:

Law I: Every body continues in a state of rest or uniform motion (i.e., constant

*velocity* without change of direction) unless acted on by a *force*.

Law II: The *acceleration* (i.e., change in *velocity* per change in time) of a body is proportional to the applied *force* divided by the mass of the body (i.e., *a* = F/*m*).

Law III: To every action, there is an equal and opposite reaction, i.e. forces are mutual.

The corresponding laws of motion in time-space (tempocosm) are as follows:

Law I: Every vehicle continues in a state of uniform motion (i.e., constant

* legerity* without change of direction) unless acted on by a *rush*.

Law II: The *expedience* (i.e., change in *legerity* per change in length of travel) of a vehicle is proportional to the applied *rush* divided by the *vass* of the vehicle (i.e., *b* = *Γ*/*n*).

Law III: To every action, there is an equal and opposite reaction, i.e. *rushes* are mutual.

Newton’s law of gravity in space-time states:

1. Every mass attracts every other mass.

2. The *force* of gravity is directly proportional to the product of their masses.

3. The *force* of gravity is inversely proportional to the square of the distance between their centers of mass.

4. The *force* of gravity is directed radially toward the larger mass.

Thus F_{g} = G *m _{1}m_{2}*/

*d²*with space-time gravitational constant G.

The corresponding law of *levity* in time-space states:

1. Every vass attracts every other vass.

2. The *rush* of levity is inversely proportional to the product of their masses; i.e., directly proportional to the product of their *vasses*.

3. The *rush* of levity is inversely proportional to the square root of the distance between their centers of vass.

4. The *rush* of levity is directed radially toward the larger vass (or smaller mass).

Thus Γ_{h} = *H* / (*m _{1}m_{2}√d*) with time-space levitational constant

*H*.

While this was presented in 1D space and 1D time, for time-space it may be generalized to 3D time and 1D space. In particular, the time, legerity, expedience, and rush are 3D vectors in time, or 4D vectors in time-space.
