Jogku is a Korean sport similar to football and volleyball.
2 teams face each other and the objective is to return the ball to the opponent, using their feet or shin.
Newton's second law of motion states that Force (F) is equal to mass (m) times acceleration (a)
F= m x a
In Jogku, a hard kick will move the ball farther and faster than a soft kick. The acceleration of the ball depends on how much force (kick) is applied to it.
