“It’s not the fall that hurts you; it’s the sudden stop at the bottom.” Translate this saying into the language of Newton’s laws of motion.
Solution 20DQ While falling you will have a lot of momentum as your velocity will be increasing continuously by the acceleration of gravity. With an enormous momentum you will be travelling and when suddenly it goes to zero, the change in momentum gives you an impulse. The abrupt change in momentum is the reason behind the pain you get after falling. There is nothing free in nature. If the body is elastic one, then it would be rebounded. But you are not an elastic object, so the change in momentum will damage you. There must be a force to change the momentum which you would get after hitting the ground. A huge force for a short amount of time causes the damage.
