If you were a protective headgear device designer evaluating the materials being used in another company’s design, what material would you MOST expect to see in a good protective device if it were cut open?

• Soft materials that allow air compression

• Durable materials that don't break

• Materials that pop on impact

• Aesthetically pleasing materials

During practice, a flyer (a person launched into the air) does not want to wear their headgear. Another member of the squad, a base (a person who launches the flyer and stays on the ground), asks the flyer to wear their headgear because it will not only protect the flyer, but it will also further protect the base if their heads collide. Which statement explains why this is true?

• If two heads collide without protection only one person experiences the peak force

• Energy cannot be created or destroyed, so the damage will depend on the original forces

• Peak force means the forces are distributed evenly, meaning equal damage or protection

• Air compression protects only the wearer because of Newton's Law of Disparates

Both people in a collision experience the same damage because​ (a)   means that forces are evenly distributed evenly during a collision. This is supported by our experiment that used ​ (b)  

• peak force
• 2 force meters against each other

• Newtons
• a force meter and a breakable object
• CD cases
