Newton's Laws of Motion help us understand car accidents by breaking them down into three simple ideas:
First Law (Inertia): This law says that a car that is moving will keep moving unless something else stops it. In an accident, when a car suddenly stops, the people inside keep moving at the same speed the car was going. Statistics show that about 30% of deadly accidents involve people not wearing seatbelts. Seatbelts are really important because they help stop passengers from flying forward.
Second Law (F=ma): This law looks at the force involved in a crash. The force is found by multiplying the car’s weight (mass) by how fast it is going (acceleration). For example, if a car weighs 1,500 kilograms and is moving at 30 meters per second, it has a lot of force when it hits something.
Third Law (Action-Reaction): This law tells us that when two cars crash, they push against each other with the same amount of force but in opposite directions. This explains why accidents can be so damaging and why people can get hurt. Studies show that if a car crashes at 50 kilometers per hour, people inside can suffer serious injuries about half of the time.
Understanding these laws can help us see why safety measures, like wearing seatbelts, are so crucial in a car.
