Momentum and Safety: How Changing Force Can Reduce Damage

The video explores the relationship between force and the rate of change of momentum, emphasizing how increasing the time over which momentum changes can reduce impact force and potential damage. Examples include bending knees when landing, wearing helmets, and using airbags, all of which extend impact time and decrease force, enhancing safety.
