If an object is moving at a constant velocity, which must be true?

Question

(1 point)
Its acceleration is zero.
Its acceleration is a non-zero constant.
Its acceleration is increasing.
Its acceleration is decreasing.

Answer 1

If an object is moving at a constant velocity, the statement that must be true is:

Its acceleration is zero.

This is because constant velocity means that both the speed and direction of the object are unchanged, and thus there is no change in velocity, which implies zero acceleration.
