Question: How Does Newton’S Second Law Relate To Airbags?

How do airbags relate to gas laws?

Airbags inflate quickly in the case of an accident and reduce injuries.

The ideal gas law says that rapidly changing the number of particles ( or ) make and increase rapidly.

By reacting Sodium Azide, , with excess heat, a large amount of Nitrogen gas () is created.

The balanced chemical formula for this is ..

Why is nitrogen gas used in airbags?

Why is nitrogen gas used in airbags? Sensors in the front of a vehicle detect a collision sending an electrical signal to a canister that contains sodium azide detonating a small amount of an igniter compound. The heat from the ignition causes nitrogen gas to generate, fully inflating the airbag in .

How does seatbelts relate to laws of motion?

The use of the seat belt assures that the forces necessary for accelerated and decelerated motion exist. Yet, if the seat belt is not used, the passengers are more likely to maintain its state of motion.

How does it feel to get hit by an airbag?

Any crash that causes your airbags to go off is likely to be painful, if not from broken glass, loud noises, a sudden tight hug from your seatbelt, then from an airbag blowing up in your face. It can feel like being kicked in the face and chest by a very strong but fluffy bunny.

Can an airbag kill you?

Not only can the airbag can seriously injure you, it can kill you. Second and third generation airbags, even though, they have been de-powered from the mid 1990’s, still deploy outward at 300 mph. A deploying airbag has the explosive equivalent of 20 shotgun shells. … This can cause neck fractures and brain injuries.

How does Newton’s second law apply to airbags?

Laws/Forces At Work The main Law at work here is newton’s second law. If there is no equal and opposite force to stop your head from moving, it will keep accelerating like it was while you were driving. That’s where the airbag comes in. Airbags work with accelerometers and explosions in order to save lives.

What force in Newtons does the airbag exert?

What force, in newtons, does the airbag exert? 15000 N D. The dummy has a mass of 50 kg (110 lb).

How does Newton’s third law apply to car crashes?

Newton’s Laws Applied to Collisions. Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.

What gas is produced in an airbag deployment?

nitrogen gasThe answer would be found in a fascinating chemical called sodium azide, NaN3. When this substance is ignited by a spark it releases nitrogen gas which can instantly inflate an airbag.

How much force is needed to deploy an airbag?

Typically, a front airbag will deploy for unbelted occupants when the crash is the equivalent of an impact into a rigid wall at 10-12 mph. Most airbags will deploy at a higher threshold — about 16 mph — for belted occupants because the belts alone are likely to provide adequate protection up to these moderate speeds.

What are the 3 laws of motion?

The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action, there is an equal and opposite reaction.

What is the force of an airbag?

In fact, the maximum pressure in an airbag is less than 5 psi—even in the middle of a crash event. Advanced airbags are multistage devices capable of adjusting inflation speed and pressure according to the size of the occupant requiring protection.

How do airbags relate to Newton’s first law?

Newton’s first law applies to air bags, seat belts, and headrests in terms of keeping your body at rest while you are driving, which in turn will keep you safe.

What happens if an airbag is underinflated what would be the cause?

If the air bag is under inflated or inflates too quickly, the passenger will still be injured by the steering wheel. If the air bag over inflates or inflates too slowly, the passenger will hit the inflating airbag and be injured.

How do airbags keep you safe?

Airbags are passive safety features designed to mitigate or prevent injuries among drivers and passengers in the event of a crash. … The deployment of a airbag protects the head and upper body of the driver, and reduces some of the force exerted on the driver by the seatbelt.
