car crashes
Two cars are travelling down a highway at 100 km/h in opposite directions. Both drivers are tired fromdriving all day and cross over the yellow line and hit head on. Crash! The driver of car A has remainedinside the car and has broken ribs due to hitting the steering wheel. The driver of car B however is on thehood of car A and is pronounced dead at the scene, cause of death, a severe case of disobeying the laws of Although both cars were heading at the same velocity one driver ended up dead while anothersurvived. This seems like a complicated and hard thing to explain and to the untrained person it may seemthat driver A just had plain luck on his side however this is untrue. Using the knowledge of basic physics Ihope to explain why the outcome for each driver was different and could have been avoided. Sir Isaac Newton was the first man to explain what happens in a collision even before automobileswere invented. He proposed the idea that an object in motion will continue in motion with the same speedand direction unless acted upon by an outside, unbalanced force. His theory is better known as the Law ofInertia. The driver of car B was not wearing a seatbelt and as a result was not connec
With abetter crumple zone comes an increase in the time of collision which results in a large decrease in force. After careful researchengineers came up with airbags that in combination with a seatbelt can increase a passengers safety in afrontal collision. If a car exerts a smallforce on a brick wall because its speed was low then the car and its passengers will experience a force ofequal magnitude but it will be in the opposite direction. Another safety feature that is less obvious to many car buyers is crumple zones. This force is only exerted on the body for the time it takes tobring the car to rest which is approximately 0. They also work with manufacturers to come up with ways to reduce injuries that occurfrom car accidents. Without a crumple zone the vehicle rebounds in an elastic mannerregaining nearly all it kinetic energy. Sensors on the car detect a high rate of decelerationinside the passenger compartment and cause the airbag to deploy and within fractions of a second of beinginflated it deflates. For many decades people have used the laws of physic to explain the event of car crashes. While the seatbelt helps in most casessometimes it isn't good enough and the driver is injured by the steering wheel. The conservation ofmomentum is often very obvious in a collision on a slippery road where friction is very small. Each of theses new items is being created to improve the safety of passengers by lookingcarefully at the physics of collisions and using Newton's three laws of motion. So airbags greatly reduce a person who is wearing a seatbeltand is involved in a head on collision from fatal injury. I hope that this informationhas provided you with a better understanding of what happens in a car crash and has provided you withenough reason to obey speed limits and to wear a seatbelt at all times while moving in a vehicle becauseremember it's not only the law, its the law of inertia!.
