Research Paper On Newton's First Law Of Motion

Newton's First Law of Motion says that unless an outside force acts on an object, the object will continue to move at its present speed and direction. Unless the objects inside the car are restrained they will continue moving at whatever speed the car is traveling even if the car is stopped by a crash. Changing or stopping an object's momentum requires a force acting over a period of time. If momentum changes instantly, as in a car crash, the force is very, very great! In a head-on collision, if a passenger flies into the dashboard of a car, their momentum is instantly stopped, and serious injury is often the result. If the passenger is restrained by a seat-belt, their momentum is reduced more gradually by the constant and smaller force of
the belt acting over a longer period of time. This is a very good example of Newtons first law of motion.
Air bags, on the other hand, help distribute the force exerted on a human body during an accident to minimize the deceleration rate and injury. This is also an example of newton's first
law. These are the ways newton’s laws help you become a better driver.Same cars are safer than others because of their structural design. A good structural design has a strong occupant compartment. Some cars are also safer because of their size. The laws of physics dictate that larger and heavier cars are safer than lighter and smaller ones. The most important reason some cares are safer are because of their restraint systems.
Belts, airbags, and head restraints are examples of these.There are many seat belt styles. The one that comes in most cars are the sash seat belt. This is probably the most effective seat belt because it supports your whole body in a crash. The second most popular seat belt is the lap seat belt which is only found in air planes and old cars. It does not support your whole body but will work just as well.Over 37,000 people die in road crashes each year. Over 1,600 children under 15 years of age die each year. Nearly 8,000 people are killed in crashes involving drivers ages 16-20. 40 % of accidents are caused by alcohol, 30% are due to spreading, and 33% are due to reckless driving.The most recent number say that 109,554 crashes happened in 2014 and 708 were fatal. The amount of urban accidents was 89,352 with only 397 being fatal. The number of rural crashes are 20,202 with 20,202 being fatal. There is little difference between fatal rural and urban car crash fatalities. Car crashed last year in Arizona that involved teens were 7,764. The number of crashes due to alcohol were 390. There are many reasons to wear a seatbelt. The main reason is it might save your
live. But how does it do this. In this brochure I will be explaining why seatbelts save lives.When there is a car crash, the car, its contents and the passengers decelerate rapidly. They experience great forces because of the very large deceleration, which can cause injury. Upon sensing a collision the seat belts lock in place. When the car crashes, there is no unbalanced force acting on the person, so they continue forward. The person moves against the seat belt, exerting a force on it. The seat belt then exerts a force back on the person. This causes a controlled deceleration of the person. Seat belts are designed not only to keep you from being thrown from the car, but also to absorb the impact of a crash where your body can withstand it best -- in the bones of your hips, shoulders, and chest, according to the NHTSA. Seat belts also stretch slightly so your body doesn't stop as abruptly, and they prevent you from colliding with a part of the car or another person.
