Newton's Laws of Motion are also very present in the game of soccer.
Newton's First Law of Motion states that an object in motion will remain in motion unless acted upon by an outside force; an object at rest will stay at rest unless acted upon by an outside force. This is very evident when the ball is in the air. The ball would stay in the air forever if it weren't for gravity and drag. Gravity pulls the ball down toward the Earth and drag, the friction of air acting in the opposite direction of the ball, slows the ball down. Another example of this is evident when a ball is sliding across a field and then slows down and stops. Now at first the ball was at rest on the ground, not moving. Once the force acted on it, (a big burly soccer dude), the ball is set into motion where Newton's Laws take over. The friction of the ground causes the ball to slow to a stop and also air resistance opposes the ball and brings it to a stop. Newton's Second Law states that the
acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be very easily be stated using the equation: F=ma. In this case F is the net force, m is the mass of the object, and a is the
acceleration of the object. This can be seen when you kick the ball, the more force you use to move the ball the greater the acceleration of the ball.
Newton's Third Law of Motion states that for every action there is a an equal and opposite reaction. Just like if you start hollering at the referee during a game, he's going to yell back and make you go sit your butt down. Every time you go to kick the ball this law comes into effect. You may not realize this because we are so massive compared to the ball that we do not realize that the ball actually pushes back on our foot as we push against it.
