In a car crash, there's a rule called Newton's Third Law of Motion. It says that for every action, there is an equal and opposite reaction. This means that when cars crash, they push against each other in ways that affect both the cars and the people inside them.
Action Force: When car A hits car B, car A pushes against car B. This pushes car B forward or changes its direction.
Reaction Force: At the same time, car B pushes back against car A with the same strength. This push can change how car A moves, possibly causing it to crash or veer off course.
Action Force: When a crash happens, the car suddenly slows down. If a passenger isn't buckled up, their body keeps moving forward, just like the car was moving before the crash.
Reaction Force: The seatbelt (or airbag) then grabs the passenger and makes them slow down quickly, helping to stop them and reduce the chance of injury. This shows how passengers interact with the safety features of the car.
In 2020, about 38,680 people died in car crashes in the United States, according to the National Highway Traffic Safety Administration (NHTSA).
Wearing seat belts can lower the chance of death for front-seat passengers by 45% and the risk of serious injuries by 50%.
The force during a crash can be calculated with the formula: where:
( F ) = force
( m ) = weight of the vehicle
( a ) = how quickly the speed changes (also known as acceleration)
Let's say you have a car that weighs 1,500 kg and is going 30 meters per second before it suddenly stops within half a second after hitting something:
First, we find the deceleration ( a ):
Now, we can calculate the force during the crash:
This means that a very strong force acts on both the car and the people inside during a crash. Understanding these action and reaction forces is really important for making cars safer and protecting passengers.
Car crashes are a great way to see Newton's Third Law of Motion in action. The push and pull between crashing cars and the effects on passengers show just how important it is to have safety measures in place. Knowing about these forces can help lessen injuries and save lives on the road.
