What is angular momentum in throwing?
Angular momentum, which is also called rotary momentum is a mechanical factor in discus throwing that basically describes how fast the thrower+discus system is rotating (speed of rotation). In this respect, angular momentum is also related to how “spread out” the system may be with respect to the axis of rotation.
What is the mass of a discus?
One of the sport’s throwing events, athletes throw a metal disc weighing 2kg for men (22cm in diameter) and 1kg (18cm in diameter) for women, as far as possible while remaining inside a 2.5-metre diameter circle.
How does the discus work?
discus throw, sport in athletics (track and field) in which a disk-shaped object, known as a discus, is thrown for distance. In modern competition the discus must be thrown from a circle 2.5 metres (8.2 feet) in diameter and fall within a 40° sector marked on the ground from the centre of the circle.
How much does a discus way?
The discus weighs 2.2 pounds (1 kg) for women, and 4.4 pounds (2 kg) for men. This medal disc is thrown by the athletes inside a circle, which the athletes cannot step out of. However, the athletes can touch the edge of the circle, which has a diameter of 2.5 meters.
What is angular momentum in simple words?
angular momentum, property characterizing the rotary inertia of an object or system of objects in motion about an axis that may or may not pass through the object or system.
How is force used in discus?
In order to produce the most force and have a further throw, then the acceleration of the spin should be as fast as possible. The force that keeps the discus against the fingers during the spin is force normal, which is the force of the discus pushing back on the hand while centripetal force keeps it in place.
Which way does a discus spin?
The fingers should lie flat on the discus. The release is initiated with the pulling of the little finger working to the index finger. For a right-handed thrower the turning of the discus should be in a clockwise direction, for a left-handed thrower in a counter clockwise direction.
What is the sector angle of discus throw?
34.92 degrees
The discus is thrown from a circle into a sector of 34.92 degrees.
What is the another name of angular momentum?
In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum.
What is the importance of angular momentum?
The concept of angular momentum is important in physics because it is a conserved quantity: a system’s angular momentum stays constant unless an external torque acts on it. Torque is the rate at which angular momentum is transferred in or out of the system.
Why is angular momentum so important?
In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant.
Why do you spin in discus?
Why? The spin on the discus stabilises it in flight. The more it spins, the more it resists tipping or tilting over, allowing it to stay in the air for longer. Think of a frisbee.
Why are shot putters fat?
The Kiwi stands 1.83m tall and weighs 129kg. Shot putters need their size in part in order to be able to “get behind” the implement – which for men hits the scales at 7.26kg. The linear glide technique is being supplanted by the rotational method more and more among many elite males.
