Newton's Third Law of Motion - Science of NFL Football

The video tutorial explains the physics behind tackling in NFL, focusing on Newton's third law of motion and the concept of momentum. It describes how momentum, defined as mass times velocity, plays a crucial role in tackling. The tutorial uses Newton's cradle to illustrate the conservation of momentum and differentiates between elastic and inelastic collisions, highlighting that football collisions are typically inelastic. Effective tackling techniques are discussed, emphasizing the importance of stopping the ball carrier's forward progress by directing energy efficiently.
