This weekend I played two soccer games. I was kicking around a soccerball afterward to work on some of my skills that I needed to improve on for the next games. I noticed that there was a physics concept in kicking the ball. It is related to Newton's first law. This law states that an object remains at rest or maintains a constant velocity unless a net force acts upon it. Before I kicked the ball, it didn't have any motion. It had a constant velocity of 0m/s. My foot is the exteral net force that acts upon the ball causing it to change its velocity. The ball will not move unless I kick it just like any object will stay at rest unless a net force acts upon it. It also works the other way too. An object that is in motion will stay in motion unless a net force acts upon it. So, the ball will roll at constant velocity (pretending there is no friction) unless my foot touches it . This weekend I realized that there was physics in a game as simple as soccer.
