What happens to the brain when football players are hit? Scientists placed sensors in their helmets to find out. Which two things did these sensors measure?
A how fast the head moves when players are hit
B how fast players are running before they are hit
C the direction the head moves when players collide
D the location of the ball when players are hit
E how much the players weigh at the time of a tackle
The correct answers are:
A) how fast the head moves when players are hit
C) the direction the head moves when players collide
Explanation: Scientists use sensors in football helmets primarily to measure the force and dynamics of impacts. These sensors track how fast the head moves upon impact (A) and the direction in which the head moves during collisions (C). This information helps researchers understand the effects of hits on brain health and injury risk. If you have more questions about this topic, feel free to ask!
