Yep... well, it reverses the direction of acceleration. If the object is accelerating from a stationary position, the direction of motion is reversed.

No.
If an object is moving in the positive direction with some positive acceleration (a), reversing the acceleration (now -a) will not immediately change the direction of motion.
The direction of acceleration does not necessarily correlate to the direction of motion.
It is certainly possible to be accelerating in one direction, but moving in the opposite direction.
For example, if you threw a ball into the air, it will be traveling upward for a period of time, but the force of gravity is accelerating the ball downward towards the ground. Eventually the ball’s velocity will change so that it will be traveling downward in the same direction as the acceleration…but as we can see, it is not a requirement.

The negative represents the force in the opposite direction.
Not necessarily resulting in a change of direction, maybe just a deceleration.

all of them do. Venus and Mercury are specific situations. As they are interior our orbit they seem to head around the sunlight, at times transferring in advance of it, at times falling in the back of. The outer planet tutor retrograde action because of the fact we orbit speedier than they do, so each and every 3 hundred and sixty 5 days we seize as much as them nad bypass them, at which element they seem to head backwards relative to the celebrities.

NO.....it reverses the acceleration. some call it decceleration, not a good term.
