B) The net force on the object is in the forward direction.
C) No forces are acting on the object.
D) The acceleration of the object is in the forward direction.

Quizplus · Accepted Answer

If an object is moving forward with a constant velocity, that means the acceleration is zero. According to Newton's second law, F = ma, if the acceleration is zero, then the net force on the object must also be zero. Therefore, choice A is the correct answer. Choices B, C, and D are all incorrect because they do not necessarily have to be true for an object to be moving forward with a constant velocity.
