Wouldn’t that imply the velocity changes? Even if that velocity is extremely small, for the system to come to rest again, wouldn’t there have to be a net force eventually in the opposite direction to cause it to stop? So, how does a system from a state of rest move through a compression or expansion, and then come to rest again without there being a net force in the opposite direction at some point in the process? | |
