Explanation:

According to Newton's first law of motion, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. When the net force acting on an object is zero, there is no unbalanced force to change its state of motion. So, its acceleration is zero.

Answer:

acceleration
