1. Many people make the mistake of believing that when a larger defensive player collides with a wide receiver who
is making a catch in the air, the larger defender must be exerting a bigger force on the smaller receiver, leading to
a greater chance of injury. This, however, is not true. Explain why and which of Newton's 3 laws supports your answer.

Both football players exert the same magnitude of force as explained by Newton's third law of motion.

Explanation:

It is not true that the larger defensive player exerts a larger force on the smaller receiver because when both players collide in the air, they exert equal magnitude of force on each other.

This is explained by Newton's third law of motion which states that for every action, there is an equal and opposite reaction. For example, when the two football players collide in the air, there is an equal action force in the collision while they both equally react by falling or moving apart.
