Answer:
During a collision a quantity called momentum is conserved. When the car slows down during impact its momentum decreases. As it decreases, the passengers feel a force which can result in injury,
A larger impulse means that a greater force is experienced by the occupants of the cars. When cars crumple together, there is a smaller change in momentum and therefore a smaller impulse. The smaller impulse means that the occupants of the cars experience a smaller force.
