Discus
There are several Olympic sports played every four years, discus is one of them. In 708 BC discus started in Germany. In 1986, discus became an Olympic sport. The discus is one of the four throwing events. In track and field at the Olympics. Also, the equipment an athlete needs to play this game is a cage, and a disk to throw. Last, the rules an athlete must follow. They can touch the inner rim. And they cannot touch the ground beyond the cage. The weight of the discus is fixed at 2 kg for men and 1 kg for women. To be successful at discus, an athlete must practice. Discus also shows many concepts of physics.
The discus has many different forces at work. To begin, balanced forces are something at rest. Balanced forces can be seen in the sport of discus when the disk is on the ground and when players are standing still because these things are not moving. Also, in these instances, the force of the ground and the force of the objects, feet or disk, are pushing against each other equally-causing no motion. Unbalanced forces are something in motion. These types of forces can be seen in the sport of discus when the disk is being thrown in the air. This is an unbalanced force because it is in motion. Newton's first law of motion says an object in motion stays in motion until a force acts on it. An object at rest stays in rest until a force acts on it. Last, in the game the way Newton's law works in discus is the person throws the disk into motion the disk stays in motion until gravity pulls it down. Overall, Newton’s first law can be seen throughout discus.
Additionally, here is another law that can be seen in discus. Newton's second law says the greater the mass the greater the force required to move it and the less mass the less force required to move it. A force is a push or pull. There are two kinds of forces, unbalanced and balanced. Forces in my sport are muscles. Mass is the amount of matter or particles in an object. Solid particles are close together that makes it heavy. Examples in my sport of masses are the net, player, and disk. The net has more mass because it is bigger and has more particles, and the disk has less mass because it has fewer particles. Acceleration is a change in velocity. Velocity is a change in speed or direction. The acceleration of the disk is impacted by the throw. A harder throw and the disk will go farther while a softer throw the disk will go not far. This is how the player accelerates the disk. Athlete’s in discus can predict how far the disk goes by increasing the force for a harder throw and decreasing the force for a softer throw. Athletes can change the direction of the disk by letting go of the disk where they want it to go. Clearly, Newton’s second law can be seen throughout discus.
Next, Newton's third law is also seen in discus. To begin, the law. Newton's third law says: for every action there is an equal and opposite reaction. Also, the examples. The first action is an athlete throwing the disk, the reaction is the disk going forward. Another action is the disk going through the air and the reaction is the disk hitting the ground because of gravity. Truly, physics can be seen throughout the world in discus. Clearly, discus is amazing and fun. Physics can be seen throughout every movement in this sport.
