1.03 The Laws of Motion

Soccer

Newton’s First Law of Motion: This can be seen in soccer when ever the match starts. The ball does not move until a player kicks it. The kick applies the unbalanced force that it necessary to get the ball to move since the ball is the Object that is not in motion. Once this unbalanced force of the kick is applied to the ball it will move. And since the ball is moving in a single direction at a constant speed another unbalced for is used to stop it. Friction comes into play here. Since the ball is moving across the field it is creating friction between itself and the ground. This is what eventually slows the ball down and brings it to a stop. If there was no friction between the ball and the field then the ball would just keep going unless someone put their foot in front of it or it hit a wall.

Newton’s Second Law of Motion: This law can be seen when a player kicks the ball. When a player kicks the ball he applies force to it. And if the player uses a large amount of force to kick the ball and there is nothing applying force to the ball in an opposite direction then the net force will be large. But since the acceleration of an object is also affected by the mass of an object, the size of the soccer ball also comes into effect. If a larger ball is kicked with the same force as a smaller ball then the smaller ball will have the greater acceleration. If Player A kicks the ball towards the goalkeeper with a force of 5 in the direction of the goalkeeper, but the goalkeeper kicks the ball towards the player with a force of 10 then the net force would be 5, but the ball would be moving back to the player that kicked it at the beginning, since the goalkeeper
