GENERAL KNOWLEDGE

Detailed explanation-1: -According to Newton’s third law, when a body A exerts a force on another body B, B also exerts an equal and opposite force on A. Hence, while kicking a ball, the footballer’s leg will experience the same magnitude of force by which it kicked on the ball but, in the opposite direction.

Detailed explanation-2: -First Law of Motion The first law says that any object in motion will continue to move in the same direction and speed unless forces act on it. That means if you kick a ball it will fly forever unless some sort of forces act on it! As strange as this may sound, it’s true.

Detailed explanation-3: -So, the unbalanced force is the reason for the football movement, and when we kick the football, the unbalanced force acts on it. Therefore, kicking a football is an example of unbalanced force and option (B) is correct.

Detailed explanation-4: -A real-world example The ground is still, of course, and the ball doesn’t move unless someone kicks it or picks it up. When you kick the ball, you’re applying a force that changes its state: it goes from being still to being in motion. According to Newton, the ball will continue to roll in a straight line.
