Question:

An object is moving with a constant velocity. Is there a net force acting upon it? [Pg. No. 101]

Answer: Verified

No, there is no net force acting on the object. If an object is moving with a constant velocity, its speed and direction remain unchanged, which means its acceleration is zero. According to Newton's first law, zero acceleration means the net force acting on the object is zero.
