Answer:
When you play basketball, you play on a surface called a Court with 2 symmetrical halves, both consisting of a basket or net on each end. The aim of the game is to score the most points or baskets in the allotted time. Rules vary from league to league but in the NBA games last for 48 minutes with four quarters of 12 minutes. In a basic basketball game, the time limit can be changed or it can be a game of the first to a certain number of baskets.
Teams
You can play in teams which can consist of 1 to 5 players however you can also play on your own as well when practising or executing Drills. Playing with friends can be useful to help share advise and have more opportunities to learn and easily begin to understand basic basketball rules through playing regularly.
Positions
Each player has his or her own position name on the court and this is usually determined by height, speed and agility. The tallest players are usually allocated Centre position, and they are usually available to rebound both defensively and offensively as well as being the best player for tip off. These players in the NBA can range from 6ft,7 to 7ft+ The next tallest players are usually Forwards and the fastest of these are called Power forwards. The smallest players are called Guards who are usually the quickest, both physically and mentally and who co-ordinate all the plays laid down by the coach of the team.
Basic Rules
When moving the basketball around the court, the players must travel around using a technique called Dribbling. To dribble the player must not take more than a step and a half without the ball coming into contact with the court and back to the players’ hand again in a bouncing motion. If more than 1 and a half steps are taken this is a Travelling violation. Once the player has stopped dribbling they may not move again until the ball comes to them from another player. Each shot taken can be done either inside or outside the shooting Area. Outside the shooting area a successful shot is worth 3 points and inside the area is worth 2 points. However inside the shooting area, there is an area named The key in which players may not remain for More than 3 seconds to prevent goal hanging. Additional single points can be scored from the free throw line in a penalty.
These are all basic basketball rules and there are many others that need to be obeyed in order not to violate the rulebook but as a beginner are not necessary to learn until you have mastered the basics.

Newton also understood that white light can be separated into its components because each ray of color is deviated by the glass of the prism by a different amount. He realized, for example, that red light is consistently less deviated than violet light.
