[6.0] Weird deacceleration action of the ship when it's hit

[charlie1024]

Hello, the video describes the symptom at all.

It seems strange because

1. Being hit and stuck at the position is not muturely related. If the ship is hit, it must try to run and run.

2. The ship is really stuck at the position, but the velocity is not consistent compared with the behavior of the ship.
For example, the ship(Prometheus) being hit stops, or not stops. We see the ship sometimes
stop, but velocity meter doesn't go to 0m/s directly. Just decreases slowly.
But, the ship suddenly re-accelerates and velocity meter matches.

(0:11, 0:31 vs 0:50)
Former examples show inconsistency of the ship. However, later example show the ship "really" de-accelerates
(even if the ship deaccelerates with -inf m/s2...).

My Moreya deaccelerated somehow and its velocity is not 0m/s of course, but I couldn't understand
this kind of acceleration when the ship is hit is just normal situation.

Thank you.
