1. When a car crashes and suddenly stops, the passenger continues moving forward due to inertia, but airbags would instantly deploy to cushion and slow them down, which reduces the chance of getting injured. Without airbags, the passenger would hit hard surfaces, causing serious harm.

2. Car safety features like airbags and crumple zones reduce the force of a crash by increasing the time, which lessens the impact to protect the passengers. Airbags provide a cushion while crumple zones absorb energy by deforming.

3. Cars have crumple zones that are designed to be destroyed and absorb crash energy, protecting passengers by reducing the force transferred to the car. This controlled destruction increases collision time and decreases the risk of injury.

4. If a car slows down before crashing, the force on the car and person is reduced because the change in momentum isn't instant which is gentler to the object. This gives safety features like airbags more time to protect them.

Q1. What happens to the passenger when a moving car crashes and suddenly stops? When a traveling car slams and abruptly halts, the passenger keeps moving forward because of Newton's First Law (Inertia). Their body prefers to keep moving at its original speed. If they were not wearing a seat belt, they would be tossed into the dashboard or windshield. The seat belt exerts an opposing force, as dictated by Newton's Second Law (F=ma), to slow down the passenger safely. It prevents them from colliding with hard components of the car by regulating their slowing down. Q2. In what ways do car safety features mitigate the force of a crash? Car safety mechanisms such as airbags and seat belts attenuate force by expanding the time taken for deceleration, using Newton's Second Law. A seat belt also stretches a bit, taking a longer time to bring a person to a stop in motion. Airbags create a cushion, adding to that time. By distributing the impact over more time, the passenger experiences less force, minimizing possible injuries. Q3. Why are certain components of a car designed to crumple upon impact (such as the front and rear)? Front and rear crumple zones of a vehicle are intended to deform and crush upon impact. This mechanism employs Newton's Second Law by providing more time for the car to slow down. By lengthening the time to stop, the force on the passenger compartment is minimized. The crumpling dissipates and absorbs the kinetic energy of the crash, preventing injury to the vehicle's occupants. Q4. If a vehicle decelerates before hitting, how will this impact the force on the body? If a vehicle decelerates before impact in a crash, the force on the body is considerably less due to Newton's Second Law. Lower initial speed equates to less kinetic energy that must be absorbed during collision. This translates into a reduced change of momentum (Newton's Second Law) and hence lower force on occupants. With or without safety devices, lower speed at impact is far safer and less risky for serious injury.

1.) The passenger would try to change in state of motion, which causes us to usually get tossed around it it weren't for our seatbelts and other safety features. This depends on how much force was produced because of the crash.

2.) With breaking systems, it helps the decrease the force by increasing instead the time of the crash. Increasing the time gives it more time for the force to spread out, causing less damage than a quick and short crash.

3.) These crumple zones help with the lesser spread of the force across the vehicle and protecting us from impact. Since force is conserved and not changed, the force moves across the car when there is crash.

4.) This greatly affects the force since there is a difference between the impulse (change in momentum) of the car that decelerates before crashing versus one that just crashed all of a sudden. The decelerated car would have less force produced due to its impulse, thus not affecting the passenger as much, compared to a random stop, where the passenger's life would be so much more at risk.

1.When a car crashes and suddenly stops, the crumple zone of the car will help protect the passengers by absorbing and distributing the collision energy, which also increases the time where the car’s velocity changes from moving to stopping. According to Newton first law of motion the passengers will continue moving at the same velocity until acted on by an external force. The crumple zone deforms to extend the duration of the impact, reducing the acceleration giving the passengers more time to decelerate and decreasing the energy the passenger cell will absorb.

2. The car's safety features greatly reduce the force affecting the passengers hence reducing their injuries.The crumple zone helps reduce the force acted on the passenger cell by bending or crumpling. Basically they act like a cushion absorbing the energy from the crash and gradually slowing the car down instead of just stopping suddenly. Meanwhile the airbag acts like a pillow slowly slowing down the passengers instead of just suddenly stopping them reducing the g-forces acting on the passengers reducing head injury and the seatbelts keep the passengers in place during a crash making sure they don't fly off their seat during a roll over or a hard braking. To add to that the stability controls and braking systems help the passengers by reducing the chance of spinning out or rolling over during a crash and reduce the chance of brakes locking up.

3. There are parts of the car that are made to crumple to spread the energy so the passenger cell will be safer. Example back when crumple zones were not that widely used when cars crash they instantly stopped however the passengers will keep moving due to Newton's first law of motion. But now with crumple zones being widely used instead of stopping suddenly the cars will gradually stop spreading the collision energy making the passenger cell and lowering the chance of whiplash.

4. If a car slows down before stopping it will reduce the force our body will experience during the crash. By slowing down instead of stopping the acceleration will be lower, lower acceleration means less force on our body which reduces the chance of injury like brain damage, whiplash and more.

1.The stability control will help the passenger during the crash by making the car stable and preventing the loss of control or flipping over during the crash. Electronic stability control or simply ESC uses sensors to monitor a car's speed, wheel traction, and steering direction. If a car is about to lose control the ESC will help or try to prevent that from happening.

2.ESC helps reduce the force of the crash by trying to prevent it from happening in the first place. It's designed to help stabilize the car, prevent rollovers and reduce the chance of spinning out or losing control.

Some parts of the car are designed to crumple to help spread the energy across the car reducing the collision force the passenger cell will take.

If a car slows down before crashing the passenger will receive less force and the ESC helps prevent that by stabilizing the car
