Subject: Car Crash What's a car crash? Source:http://www.google.com/imgres?um=1&hl=en&tbo=d&biw=1440&bih=712&tbm=isch&tbnid=yAAJSGnynFU17M:&imgrefurl=http://www.shutterstock.com/pic-60541462/stock-vector-hand-drawn-car-crash.html&docid=tDyV5SbwKJwutM&imgurl=http://image.shutterstock.com/display_pic_with_logo/491206/491206, A car crash happens when a vehicle collides with a
pedestrian, animal, debris, or another vehicle, and could cause death, injury, vehicle or property damage. How does Newton's First Law of Motion relate to a car crash? Newton's First Law could relate to the crash when:
you have two cars accelerating toward each other,(and object in motion will stay in motion) one car sitting still, while another is heading towards it,( an object at rest will stay at rest) and then when two cars collide, causing a crash. (an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force. How does Newton's Second Law Relate to a Car Crash? Newton's Second Law is if the mass of an object remains constant, acceleration increases as the force increases. And can also be represented by F= M*A. So in a car crash, M is
your mass, A is your acceleration, and F is your force being
put on your car. When two cars are heading toward each other and they collide, the severity and some times amount of injuries, will depend on the force being put on the car. If there is a large force, there is a better chance your injuries will be more drastic. How does Newton's Third Law of Motion relate to a car crash? Newton's Third Law is that for every action, there is an
equal and opposite reaction. So when your driving forward, your moving forward on the road. What keeps you moving and going forward? The friction between your tires and the road. As the road is pushing forward on the car, the car is pushing backwards on the road. Showing Newton's Third Law, the road will push on the car forward with an equal and opposite force. http://www.road-accidents-compensation.com.au/CAR-ACCIDENTS-CAR-CRASHES.html http://www.belovedcars.com/90-of-traffic-accidents-due-to-human-error/
