Soccer is becoming more and more popular in the United States. And while other soccer-related injuries are happening less frequently, youth soccer players in the United States are experiencing more concussions. A concussion is a type of traumatic brain injury caused by the head experiencing an impact and moving quickly back and forth, causing the brain to bounce around in the skull.
A concussion can result from a force of 400–1,000 N on the head. There has been debate in different sports about 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.

Question 2
2.
There are three types of collisions that tend to happen frequently in soccer: (a) headers, (b) collisions between players’ heads, and (c) a player’s head hitting the ground.
How would the amount of force on the head compare to the amount of force on the object it collides with (another head, a soccer ball, or the ground) in each system A, B, and C?
