Here's why:
* Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
* Unbalanced Force: An unbalanced force means there's a net force acting on the object in a particular direction.
* Direction of Acceleration: The direction of the acceleration will always be in the same direction as the net force.
Therefore, if the unbalanced force is to the left, the object will accelerate to the left.
