It will remain at rest or moving with constant velocity. If the forces acting on object are unbalanced (the net force is not zero), the object will accelerate. Its speed and/or direction of motion will change.

Also called the law of inertia, this is the most important thing to realize about motion. article https://www.khanacademy.org/science/physics/forces-newtons-laws/newtons-laws-of-motion/v/newton-s-1st-law-of-motion 2023-04-30T21:01:15.828786566Z Newton's first law of motion introduction Newton's first law states that objects move with constant velocity unless acted upon by an unbalanced force. If the net force on an object is zero, it will remain at rest (if already at rest) or continue moving with constant speed and direction. A force is not required to keep an object in motion unless an opposing force is present.
