Wearing kneepads while skating and taking longer to come to rest after falling reduces the impulse applied to the knees by a factor of 3.
The impulse decreases by a factor of 3 when wearing kneepads while skating and taking three times longer to come to rest after falling on your knees. This is because impulse is the product of force and time, and in this scenario, as the time taken to stop increases, the force required to stop reduces, leading to a decrease in impulse applied to the knees.
