For the first question in this quiz, the 4th choice- the object is at rest... does that have to be true? because no acceleration implies no change in velocity.. so the object need not be at rest but move with uniform velocity and therefore have no acceleration. So no acceleration need not purely imply that the object is at rest, the object could be in motion .. but uniform motion, right?
It *could* be true that the object is at rest, which would mean zero acceleration, but it does not have to be true. It could be that the object travels at constant velocity, which also gives zero acceleration.
