I was wonder what the slowest velocity possible for an object is. According to mathematics, between any two numbers, there are an infinite number of numbers in between, so between a velocity of 0 and any arbitrary velocity there must be an infinite number of velocities. But from common knowledge and experience, objects don't slow down forever. So I suppose my question is: what is the smallest velocity an object can have before it is defined as being at rest? And why couldn't we just take that velocity and keep dividing in in half for example? Anyways, just some late night pondering any explanations would be terribly appreciated!
