- Q14In certain martial arts, people practice breaking a piece of wood with the side of their bare hand. Use your understanding of impulse to explain how this can be done without injury to the hand.Given the same change in momentum, when the time interval is bigger the impact force is smaller.Given the same change in momentum, when the time interval is smaller the impact force is smaller.Given the same change in momentum, when the time interval is bigger the impact force is bigger.Given the same change in momentum, when the time interval is smaller the impact force is bigger.30sS9FE-IVb-36
