Momentum comes into play in the scene, since the car is very heavy and its speed is quite fast, so it has a large source of momentum, the formula for momentum is P = mv. Since then, there are two types of collisions, elastic and inelastic. Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get the original essay Elastic collisions are collisions in which momentum and kinetic energy are conserved. The total kinetic energy of the system before the collision is equal to the total kinetic energy of the system after the collision. The video here is inelastic, occurs when the momentum stays the same but the total kinetic energy changes before and after the collision, they don't separate. But in this case it's inelastic, the video is everything. Principles of Physics In this video, there is a mannequin in the car that drives and then suddenly crashes into the wall. In the first law, the absence of external forces, an object at rest remains at rest and an object in motion remains in motion with a constant speed. Since there is an unbalanced force acting on the car, it will not maintain its motion and immediately decelerate to rest. The passenger will share the same moving state of the car. The passenger and the car will decelerate as one body. The second law describes that the force with which the driver hits this object is based on the mass and acceleration of the car. In the video, the driver will eventually come into contact with another object (airbag). The constant of proportionality is the mass of the mannequin, so mathematically, F=ma, where F is the force acting on the mannequin, m is the mass, and a is the acceleration. The third law here shows that airbags are created to absorb the force that your body would apply to the airbag in the event of a car accident. In every action there is an equal and opposite reaction. If this law did not exist, the car would not be damaged at all. All of these laws must be followed so that you are respected as well.Car Safety FeaturesPhysical ConceptsSeat belts and airbags are your last hope in the event of an accident, seat belts safely provide an external force that can stop your body when the car stops or slows down. Airbags work by increasing the impact time and decreasing the force of the impact, thereby preventing the dummy from being injured and killed. Without a seat belt to stop the driver with the car, the driver flies freely until brought to an abrupt stop by an impact on the steering column, windshield, etc. Without a seat belt to stop the driver with the car, the driver flies free until brought to an abrupt stop by an impact on the steering column, windshield, etc. Stopping distance is estimated to be about a fifth of that with a seat belt, causing the average impact force to be about five times greater. The work done to stop the driver is equal to the average impact force exerted on the driver times the distance traveled during the stop. When a seat belt is not used, the passenger will tend to continue in their state of movement. So,they will be propelled from the automobile then projected into the air. Impulse played an important role in video, seat belts and airbag. Understanding momentum, momentum is caused by a force during a specific time interval is equal to the change in momentum of the body during that time interval: momentum, in fact, is a measure of the change in momentum. The impulse can choose the force or the time, if the time is great like the impulse, if the force is great like the impulse. Airbags reduce the time it takes for your face to hit the steering wheel, while seat belts prevent you from reaching a distance where you're supposed to crash. Principles of Physics In the first law it states that this law is best illustrated when driving trucks or cars. In fact, a body's tendency to keep moving is a very common cause of various transportation-related injuries. For example, consider the case where a car accidentally collides with a fixed wall. When a car collides with a wall, an external, unbalanced force acts on the car, causing the car to abruptly decelerate to a stop. All other passengers inside the car are also slowed down to rest in case they are strapped in. When you are closely attached to the car, you will also be in the same state of movement as the car. When a car accelerates, passengers will tend to accelerate with it. When it decelerates, the passengers also decelerate with it. If the car travels at a constant speed, the passengers will also maintain the same constant speed. If a car stops suddenly after colliding with the wall, the passengers will not share the same state of motion as the car. The use of seat belts ensures that there are the necessary forces to accelerate or even decelerate the movement. The second law states that an object acted upon by force experiences acceleration in such a way that the force is equal to the mass times the acceleration. Mathematically this is represented by F=ma. In other words, it states that the force applied during the accident is proportional to the mass of the impacting cars. This means that the greater the impact force of cars, the greater the force applied, which implies greater destruction. The opposite is also true. If the mass of impacting vehicles is smaller, less force will be applied, meaning less destruction overall. Last but not least, the third law: This law states that action and reaction are equal and opposite. In short, for every action there will be an equal opposite reaction. The law concerns the conservation of energy and also mentions the contribution of force. Essentially, a force is defined as a push or pull on a certain object and this is due to an interaction with that object. In the context of a car accident, this means that the force with which a car crashes into a wall causes the wall to exert the same force on the hood, resulting in damage. The direction of forces will also be opposed.Feature Impacts on Passenger SafetyFrontal airbags have been standard on all new cars since 1998 and on light trucks since 1999. Most vehicles were already equipped with them. Crash sensors connected to an on-board computer detect a frontal collision and trigger the bags. The bags inflate in milliseconds — in the blink of an eye — then immediately begin to deflate. Although airbags have saved thousands of lives, they can also cause injury or death to children or occupants who do not use them..
