Volleyball is one of the most popular sports in the world. There are six basic skills of volleyball.
Serve-Used to put the ball in play. The action is done with arm swing that sends the ball over the net into the opponent's court.

Forearm Pass-Used to receive the ball from your opponents, as in service, or as a technique to accurately control the ball in a way that eliminates lifting or carrying the ball. the fundamental action of passing is to rebound the ball off of the forearms (which are held together tightly with the palms and thumbs positioned together) from a slightly squatted and balanced position.
Setting- Used to receive a teammate's pass in order that the play may continue by passing the ball overhead to an attacker. the fundamental action of setting is to contact the ball with the finger pads momentarily at the forehead and following through with arms fully extended to the hitting target.
Kill or Attack-Used to put the ball into the opponent's court in order to earn a point or side out. the fundamental action of attacking incorporates a quick approach followed by a strong, full arm swing, and follow-thru.
Block-Used to stop the ball from crossing the net as a result of an opponent's attack. A block is effective if it immediately places the ball back into the opponent's court or if it temporarily slows down the ball in order for a defender to make a dig. The fundamental action of blocking is to stand facing the net with feet shoulder width apart, arms nearly extended above the head, ready to jump above the net to deflect the ball back into the opponent's court.
Floor Defense-used to receive the opponent's attack. The key skills are digging and sprawling. The dig resembles a forearm pass from a low ready position and is used more for balls that are hit near the defender. The sprawl is a result of an attempted dig for a ball that is hit further away from the defender and resembles a dive.
Basketball is a sport played by two teams of five players on
a rectangular court. The objective is to shoot a ball through a hoop 18 inches
(46 cm) in diameter and 10 feet (3.048 m) high mounted to a backboard at each
end. Basketball is one of the world's most popular and widely viewed sports.The
National Basketball Association (NBA) is the most popular and widely considered
to be the highest level of professional basketball in the world and NBA players
are the world's best paid sportsmen, by average annual salary per player.
A team can score a field goal by shooting the ball through
the basket during regular play. A field goal scores three points for the
shooting team if the player shoots from behind the three-point line, and two
points if shot from in front of the line. A team can also score via free
throws, which are worth one point, after the other team was assessed with
certain fouls. The team with the most points at the end of the game wins, but
additional time (overtime) is issued when the score is tied at the end of
regulation. The ball can be advanced on the court by bouncing it while walking
or running or throwing it to a teammate. It is a violation to lift or drag
one's pivot foot without dribbling the ball, to carry it, or to hold the ball
with both hands then resume dribbling.
