Question on: SS2 Physics - Mechanics - Laws of Motion

Newton's first law, also known as the law of inertia, explains why seat belts are important in car safety. When a car suddenly stops or changes direction, an unrestrained object, including the occupants, tends to continue moving with its original velocity. Seat belts apply a restraining force to prevent this, in accordance with Newton's first law. Additionally, airbags utilise Newton's second law by rapidly inflating and providing a force opposite to the direction of the occupant's motion, reducing the impact force during a collision.
