An object is moving with constant velocity. Which of the following statements is true?
A) A constant force is being applied in the direction of motion.
B) A constant force is being applied in the direction opposite of motion.
C) There are no forces acting on the object.
D) The net force on the object is zero.
E) There is no frictional force acting on the object.

If an object is moving with constant velocity, it means that its acceleration is zero. According to Newton's second law, the net force acting on an object is equal to the object's mass times its acceleration. Therefore, if the acceleration is zero, the net force must also be zero. This eliminates choices A, B, and E. Additionally, if there are no forces acting on the object, it would not be moving at all. Therefore, the correct choice is D.
