Undergrad General question about how objects move nature (discrete or continuous?)

Click For Summary
The discussion centers on the nature of motion in both game physics and real life, questioning whether objects move in discrete steps or continuously. The game developer observes that in a 2D physics engine, faster objects appear to skip over space, prompting curiosity about real-world motion. It is suggested that, at a fundamental level, space-time is generally considered continuous, though some theories propose a discrete model. The conversation raises questions about how objects interact at high speeds and whether faster-moving objects take larger "steps" or "jumps." Ultimately, the inquiry seeks to understand the basic mechanics of motion in both simulated and real environments.

Hello everyone! I hope I write in right forum branch. The reason is that I have a question in my mind for a while. Maybe you can help to understand it.

So, I am game developer, and one time I was using 2d physics engine to simulate motion in game. And I found out that in that engine, for example, 2 objects exist. First object moves with speed X and second with X*2. In this simulation second object just skips 2 times space at a time. And i was curios, is the same thing heppens in real life?

Is it any smallest step that moving objects do? And how are objects move, in basic level? Do they teleport a bit forward? If some object moves 2 times faster then another object is he doing more steps or is he doing jumps for more length? Is it possible for objects to get past each other in great speed if they are doing greater step in movement?

I mean I see how objects moves every day. But how are they doing it on basic level?

I hope I dies not sound very stupid and I hope you will answer.

As far is as known, and certainly as far as we can measure, the belief is that space-time is continuous, not discrete but there ARE those who think otherwise.
 
I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
