When kicking off the ground, what is the maximum amount of force that human's can exert?
In fact, it's the same question. Over a duration approaching zero (i.e. before gravity is a significant factor), kicking a soccer ball is the same as kicking off a much much MUCH larger ball.Hmm, In a way I see what you mean. When one kicks a ball properly (football=soccer ball to me I'm afraid) one stops applying force on contact with the ball and lets the transfer of momentum from the foot to the ball move the ball forward. However it really is a very related question.
