Can something have zero velocity but positive acceleration?
zero velocity+positive accleration=an object is speeding up in a circular direction zero velocity+negative acceleration=an object is slowing down in a circlular direction Negative velocity and positive acceleration=an object is moving backwards in a straight forward line but is speeding up Negative velocity and negative acceleration=an object is moving backwards in a straight forward line but is slowing down. By the way, an object can be moving at a constant speed in a circular direction, and it is still accelerating. It just doesn’t have a positive or negative acceleration.
