Newton's second law states that applying force to an object changes its acceleration. Wearing seat belts in cars is an application of this law to reduce injuries to passengers in accidents.
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be represented by the formula F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration.
When passengers wear seat belts in a moving car, they are applying Newton's second law. The force exerted by the seat belts on the passengers increases their mass effectively, reducing their acceleration in the event of a sudden stop, thereby preventing injuries.
