D. The net force on the object is zero.

If the object's velocity is constant ... (it's speed isn't changing AND it's moving in a straight line) ... then the net force on the object is zero. (D)

Either there are no forces at all acting on the object, OR there are forces on it but they're 'balanced' ... when you add up all of their sizes and directions, they just exactly cancel each other out, and they have the SAME EFFECT on the object as if there were no forces at all.

The true statement must be "The net force on the object is zero."

What is acceleration?

  • Acceleration is a rate of change in velocity per time.
  • Acceleration a = ΔV / ΔT.

What happens when an object is moving forward with a constant velocity?

  • An object is moving with constant velocity it means there is no change in velocity so the acceleration is 0.
  • An object is moving forward so there could some friction force.
  • If the net force on the object would be in forward direction then there would be change in velocity , but here that is nit the possibility.

So, knowing above given facts we can say that the correct answer is option D that is  "The net force on the object is zero."
