What Is Motion and How Is It Defined in Modern Physics?

[Umut_G53]

I have couple of question related to what motion is;


1) What is the definition of motion in today's physics?

2) Is motion quantized? If it is; what are the effects of it?

3) Can motion be explained without spacetime?

1. Motion is a change in position of an object.

2. No, motion is not quantized.

3. Absolutely not, as spacetime is what allows us to label an objects position in both space and time.
