Question

there are three types of collisions that tend to happen frequently in soccer: (a) headers, (b) collisions between players heads, and (c) a players 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 in each system a, b, and c? a in every collision, the peak force on the head would be the same as the peak force on the other object in the collision. b in some, but not all collisions, the peak force on the head would be the same as the peak force on the other object in the collision. c in every collision, the peak force on the head would be different than the peak force on the other object in the collision.

Explanation:

According to Newton's third - law of motion, for every action, there is an equal and opposite reaction. In a collision, the force exerted by one object on another is equal in magnitude and opposite in direction to the force the second object exerts on the first. So, in all types of collisions (headers, head - to - head, and head - ground), the peak force on the head is the same as the peak force on the object it collides with.

Answer:

A. In every collision, the peak force on the head would be the same as the peak force on the other object in the collision.
