In order for an object to be in constant uniform motion ... that is, un-accelerated,
with constant speed and direction of motion ... the vector sum of all forces acting
on it must be zero.
friction
No friction, in other words a vacuum.
Dynamics is the study of relationships that exist between forces and the motion of objects.
Acceleration is defined as the change in velocity divided by the time ora = (vf - vi)/tVelocity measures the speed and the direction of an object.In uniform circular motion, the object has the same speed but it is always changing direction and so, by the definition of acceleration, the object is considered accelerating. If this acceleration doesn't exist, the object would move in a straight line according to Newton's laws of motion.
You cannot bless an object because magic doesn't exist.

friction
Resistance to the motion of an object is friction. Several different kinds of friction exist, including dry, fluid, lubricated, skin, and internal.
No friction, in other words a vacuum.
There is no such thing as "absolute motion" - neither in outer space, nor anywhere else. Motion must always be specified in relationship to some other object.
The force must couple to the object. The point of application of the force must be able to move in the direction of the force.
Erm..yes. Technically Newton's 3rd law of Motion States that, " all forces exist in pairs: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal and opposite."
The answer is "No" according to Newton's First Law. An object at rest tends to stay at rest and an object in uniform motion tends to stay in uniform motion unless acted upon by an outside force. I think you are referring to Death Valley's "Racetrack". This dry lakebed is a unique place where rocks slide around on it's surface and leave tracks. Although I don't think anyone believes particularly weird phenomena are at work, the issue of why they move (and even WHEN!) seems not to be completely resolved. (Competing theories do exist.) No. But it the regards of the rocks moving across the racetrack, seismic vibrations, however slight, can vibrate and the rocks will move towards gravity, or downhill.

The conditions in the sun's core that allows the plasma state to exist hydrogen nuclei.
Platonism is the view that there exist such things as abstract objects. An abstract object is an object that does not exist in space or time.
