According to Newton’s first law of motion, what will happen to the
motion of an object when acted upon by an unbalanced force?

When an unbalanced force acts on an object, it causes the object to accelerate in the direction of that force. This means that if you push a stationary object, it will start moving, or if you push an object that’s already moving, it will either speed up, slow down, or change direction. Essentially, unbalanced forces are the key players in stirring up the action!

Think about the classic example of a soccer ball: when you kick it (apply an unbalanced force), it doesn’t just sit there! Instead, it rolls away, changing its state of motion. Conversely, once no more forces are acting on it (like friction or air resistance), the ball will eventually come to rest, demonstrating Newton’s first law in action!
