Fall Damage
When someone falls under normal circumstances, they collide with the ground with a certain measure of force and that same force is applied on the person as in Newton's third law. The force applied to a falling person is not instantaneous, but transferred through impulse, it is essentially a change in momentum. So the force of the fall that causes the second highest amount of accidental death in the world is dependent on the impulse or J=FΔT upon impact. The time-span of the impact diminishes the force that would be potentially lethal. Therefore if someone could maneuver a squat out just in time before the impact or hit some deformable substance, the total impulse would be the same but the force is effectively reduced.
