A. Lesson 6 Soccer Assessment (9/18/2024)

Soccer is becoming more and more popular in the United States.  Currently, youth soccer players in the United States are experiencing more concussions. A concussion is a type of traumatic brain injury caused by an impact to the head, which causes the brain to bounce around in the skull.
A concussion can come from a force of 400–1,000 N on the head. People in different sports are discussing how to best prevent concussions. In soccer, one idea is to ban headers (when a ball makes contact with a head) in youth and professional soccer.

How can the forces from a header cause a concussion, even though the soccer ball is light?

Draw one free-body diagram to show the amount of peak force on the head

Choose a CLAIM by answering the question below.

There are three types of collisions that happen frequently in soccer:
(a) headers, (b) collisions between players’ heads, and (c) a player’s head hitting the ground.
How does the amount of force on the head compare to the amount of force on the object it collides with in each system A, B, and C?
