# Discus Throws at School Meet: Vector Diagram

• halb
In summary, a vector diagram is a graphical representation that shows both the magnitude and direction of a vector quantity. In discus throws, vector diagrams are important as they allow us to visualize and analyze the different forces involved, helping us improve our throws. They are commonly used by coaches and athletes at school meets to identify areas for improvement. A vector diagram can provide information on release angle, initial velocity, direction, and forces such as gravity and air resistance. However, there are limitations to using vector diagrams, as they do not account for all factors and may not accurately represent the actual forces at play.

in the school track and field meet, three competitiors participated in the senior division discus event. the second competitior threw the discus about one and a half times as far as the first, however the third competitor threw it only about four fifths as far. draw a vector digram representing the displacements of the discus for the three competitors assuming that all throws were in roughly the same direction

well, since the first thrower seems to be the baseline, give it a vector of arbitrary length and then draw the others in relation to it.

I would first like to clarify that a vector diagram is a visual representation of the magnitude and direction of a vector quantity. In this case, the vector quantity is the displacement of the discus for each competitor.

Based on the information provided, we can create a vector diagram with three arrows representing the displacements of the discus for the three competitors. The length of each arrow will represent the magnitude of the displacement, while the direction will indicate the direction of the throw.

Let's label the first competitor as A, the second competitor as B, and the third competitor as C. We know that competitor B threw the discus about one and a half times as far as competitor A. This means that the magnitude of the displacement for B is 1.5 times greater than A. Therefore, the arrow for B should be 1.5 times longer than the arrow for A. We also know that competitor C threw the discus only about four fifths as far as competitor A. This means that the magnitude of the displacement for C is 0.8 times that of A. Therefore, the arrow for C should be 0.8 times the length of the arrow for A.

Since all throws were in roughly the same direction, we can draw the arrows in a straight line. The arrow for competitor A should point to the right, indicating the direction of the throw. The arrow for competitor B should also point to the right, but it should be longer than the arrow for A. The arrow for competitor C should also point to the right, but it should be shorter than the arrow for A.

In conclusion, the vector diagram for the discus throws at the school meet would consist of three arrows representing the displacements of the discus for competitors A, B, and C. The length of the arrows would be proportional to the magnitude of the displacement, and the direction would indicate the direction of the throw. This diagram would accurately represent the information provided and help us understand the differences in the throws of the three competitors.

## 1. What is a vector diagram?

A vector diagram is a graphical representation of a vector quantity, which includes both magnitude and direction. In the context of discus throws, a vector diagram can show the trajectory of the discus as well as the direction and magnitude of the forces acting on it.

## 2. Why is it important to use vector diagrams in discus throws?

Vector diagrams are important in discus throws because they allow us to visualize and analyze the different forces acting on the discus, such as the release angle, initial velocity, and gravity. This can help us understand how these forces affect the flight of the discus and make adjustments to improve our throws.

## 3. How are vector diagrams used in discus throws at school meets?

At school meets, vector diagrams are typically used by coaches and athletes to analyze and improve their discus throws. By plotting the trajectory of the discus and the forces acting on it, they can identify areas for improvement and make adjustments to their technique.

## 4. What information can be obtained from a vector diagram in discus throws?

A vector diagram in discus throws can provide information on the release angle, initial velocity, and direction of the discus, as well as the forces of gravity and air resistance. It can also show the optimal trajectory for a successful throw and help identify any areas for improvement.

## 5. Are there any limitations to using vector diagrams in discus throws?

While vector diagrams are a useful tool for understanding discus throws, they do have some limitations. For example, they do not take into account other factors such as wind and air density, which can also affect the trajectory of the discus. Additionally, they may not accurately represent the actual forces acting on the discus, as they are simplified representations of the complex physics involved in discus throws.
