What are some basics I need to know about basketball?

When a player makes a shot, they score two points and the ball goes to the other team. If a basket, or field goal, is made outside of the three-point arc, then that basket is worth three points. A free throw is worth one point. Fouling a shooter always results in two or three free throws being awarded the shooter, depending upon where he was when he shot. If he was beyond the three-point line, then he gets three shots. Other types of fouls do not result in free throws being awarded until a certain number have accumulated during a half. If he makes his first free throw, he gets to attempt a second. If he misses the first shot, the ball is live on the rebound. Each game is divided into sections. All levels have two halves. In college, each half is twenty minutes long. In high school and below, the halves are divided into eight (and sometimes, six) minute quarters. In the pros, quarters are twelve minutes long. There is a gap of several minutes between halves. If the score is tied at the end of regulation, then overtime periods of various lengths are played until a winner emerges. At halftime, the teams switch goals. The game begins with one player from either team at center court. A referee will toss the ball up between the two. The player that gets his hands on the ball will tip it to a teammate. This is called a tip-off. In addition to stealing the ball from an opposing player, there are other ways for a team to get the ball. Hope this helps ya! If you need anything else just ask :)
