11.B.2.1.c

define the change in momentum as an impulse (Δp̅ = mΔv̅ =F̅oveΔt)  relate impulse to acceleration and Newton's second law of motion (Δp̅/Δt=ma̅=F̅) and apply the concept of the impulse to explain the functioning of a variety of safety devices; e.g., airbags, collapsible frames, bumpers, seat belts in cars, restraining nets and crash barriers on highways, collapsible steering wheels, padded dashboards, padded helmets, padded goggles, and padded gloves, all of which are designed to increase the stopping time or time of contact by reducing acceleration and, thereby, force
