P2a Forces and Their Effects
... Car safety: The force on a passenger will be large if there is a large change in momentum in a short time. The key to safety is to extend the time of impact to reduce the force. This is done by: seat belts stretch a little, crumple zones at the front and rear, air bags to cushion the impact. ...

17.5 Acceleration and Newton`s 2nd law of motion
... About 100 years later, Newton’s second law explained why. A heavy object experiences a stronger pull from gravity than a light object, but it also has more inertia which makes it harder to get moving! The two effects cancel out, so all objects fall to Earth a = F1/m1 = F2/m2 with the same accelerati ...
