An object has an acceleration of 0 m/s squared. Does this mean that the object must be stationary. Explain.

Question

Stationary means that the object does not move.

I don't think that the object must be stationary in this case because the scalar zero only tells us that the speed of the object does not change, but it's directions might. So it all stays constant.

How does my answer look?

Answer 1

Your answer is correct, except for one thing in your explanation. If an object's direction changes it must be moving,. A direction change requires acceleration, even if the speed stays the same.
