Sitting volleyball
There are several Olympic sports played every four years. Sitting volleyball is one of them. Sitting volleyball was first played in 1956 in the Netherlands. In 1980 sitting volleyball began in the Arnhem, Netherlands olympics. The equipment needed for sitting volleyball are a volleyball and a net in the middle of two teams. The rules in sitting volleyball are that teams can only have a total of three contacts per side before it must go over the net. The first team to get to 25 points is the winner. Athletes must have one body part in contact with the floor at all times. Athletes are also allowed to kick the ball but they do not earn points.
Forces are at work all the time in sitting volleyball. Balanced forces do not move. Examples of balanced forces in sitting volleyball are the net, ball and player because the forces that move them are not applied to them yet. Unbalanced forces are the moving forces. The unbalanced forces in sitting volleyball are the ball, net and the player. These are unbalanced forces because someone or something puts a force on them. Newton's first law says an object will stay in motion or rest until a force acts upon it. The ball is at rest until the player hits the ball and the ball is in motion until another player stops it by hitting it back or to the ground. Clearly, Newton’s first law is seen in sitting volleyball.
This is Newton’s second law of mass. The greater the mass the greater the force to move it. A force is a push or pull. There are two kinds of forces, balanced and unbalanced. Forces in my sport are the ball, the player, and the player's muscles. Mass is the amount of matter something has. Examples of mass in sitting volleyball are the player and the ball. Acceleration is velocity, or change in speed or direction. The acceleration of the ball goes over the net. The force of the player hits the ball to send the ball over. The harder a player hits the ball, the farther the ball will go, or the faster the ball will go.The acceleration of the player hits the ball and you need to apply a harder force so it lands on the floor. Overall, Newton’s second law can be seen throughout paralympic volleyball.
There is one final law that effects paralympic volleyball. Newton's third law says for every action there is an equal and opposite reaction. Action is movement. Examples of movement are, balls flying in the air, and athletes hitting the ball. Reaction is the force of it. An example of action and reaction is a person hitting the ball [action] and the person going backwards
[reaction] to hit it back. Paralympic volleyball is very entertaining and also shows Newton's law of motion.Truly, paralympic volleyball is hard and fun. Newton’s laws can be seen throughout every movement of this sport.
