In one or more complete sentences, explain how natural laws apply to the following scenarios:
How does inertia affect a person who is not wearing a seatbelt during a collision?
Before a collision occurs, a car is going a certain speed. A collision causes the car to stop or slow down drastically. Everything that is in the car will still be going the same speed that the car was going, unless it is either stopped by a seatbelt or held down in some other way. A person in a seatbelt, would stop with the car, while a person without a seatbelt would follow its path of inertia keep moving. This could result in the person without a seatbelt being severely injured or even killed.
How does kinetic energy affect the stopping distance of a vehicle traveling

Because it needs less energy to stop, it takes less time. A large vehicle weighs more, therefore it takes more energy to be completely stopped. Because it needs more energy to stop, it takes more time.
Keeping in mind the kinetic energy of a moving vehicle, how can a driver best prepare to enter sharp curves in the roadway?
It is always important to keep in mind the requirements of the vehicle you are driving. If you have a larger vehicle, you may want to begin slowing down quicker than you would if you were driving a small car. This is because your vehicle has more mass and more energy is required to stop it. However, if you are driving a small vehicle, you may want to slow down a bit later than you would if you were driving a smaller vehicle so it has enough momentum to make the

The faster you drive, the larger the force of impact your car has. This being said, if you were going 60 mph and you crashed into a object, the force of impact would be sudden and jerking. You would definitely feel the impact and are more likely to be injured. However, if you were going 10 mph and you crashed into an object, the force of impact would still be evident, but you would be less likely to be jerked roughly and injured. If you were in a small compact car going 45 mph and are hit by a semi, your injuries are likely to be catastrophic and the driver of the semi’s injuries are likely going to be minor. This is because the semi is larger and has more energy than the small compact car.
Imagine you are taking a road trip! Select a destination and navigate the trip. Answer the following questions in one or more complete sentences:
Where will you go on your trip?
I would like to travel out west.
You approach a railroad crossing with a crossbuck sign that has no lights or gates. What should you do?
I should treat the crossbuck sign as a as a yield sign. I should slow down, look, and listen for an oncoming train. I should be prepared to stop if I see or hear a train
When the car is moving at 70 mph, the passenger/driver is moving at 70 mph. if the car suddenly hits a wall. the car stops moving, but the passenger is still moving at 70 mph... the seat belt prevents the passenger from flying out of the windshield / cutting their head open on the windshield. (this is based on inertia)
you could run right through and get hit or hit a train. Never pass a car that is going your
Before entering a sharp curve, the kinetic energy of the moving car is very high, to prepare for this curve, the driver can slow down the vehicle to reduce its kinetic energy to stay safe.
What it means: This means the older heavier car will have a higher stopping force which immediately puts it at a disadvantage to the modern, smaller car. However because Impulse is Force x Time and remains constant, we can decrease the Stopping Force by increasing the collision Time.
With the evidence given in the crash report involving the Volkswagen Passat and the Ford Transit van, the ultimate outcome of the velocities of each vehicle resulted in an elastic collision. An elastic collision is the end result of when two objects collide and instead of bouncing off of each other, the two objects are stuck together ( Urone, 294). Given from the crash report provided, both of the drivers were driving through an area with the speed limit at 35 miles per hour. With the evidence given, the likelihood of the collision was due to a driver exceeding the speed limit which would require a longer extended period of time that would be required to stop compared to if both vehicles were following the posted speed limit. From the photographs
We need to be very cautious when around railroads and railroad crossings. If you get in a car-
However, you should take every track and railroad crossing serious. It is better to be a little late to your destination than to never arrive at your destination. There are many warning devices and signs to let you know that you are coming to a train crossing. If you are paying attention to your surroundings, there should be no reason to have a train related accident. Advance warning signs are placed before any crossing that tell you to slow down, look, and listen.
all you have the possibility of being hit by the train. Trains always have the right of way no matter
Newton’s First Law (aka inertia) states that an object in motion will stay in motion with the same speed and direction unless acted upon by an unbalanced force. If a car was travelling at 80km/hr, everything inside the car including the passengers will also be travelling at 80km/hr. If that car hits a brick wall, the car would stop moving but the passengers would continue moving at 80km/hr until they hit a solid object such as the headrest or the wall unless they were wearing a seatbelt. Seatbelts also stretch when force is applied, which helps dissipate the inertial energy and reduce the speed at which the passenger is travelling.
Mass, kinetic energy, and stopping distance have a direct relationship so if the mass of the vehicle goes up, the kinetic energy increases, and so does the braking distance. This can be proven by the equation KE= 1/2mv2, as mention in the answer to the previous question. Assuming the vehicles’ velocities are the same, mass is directly correlated to kinetic energy. Kinetic energy and stopping distance have a direct relationship, as explained in the previous answer.To prepare to enter sharp curves, a driver should slow down. Lowering the velocity of a car decreases the kinetic energy in the car. This means the braking distance would be shorter since there is less kinetic energy to convert. Drivers that travel at a slower speed and have a short braking distance can pass through sharp curves easier because they have more control over the vehicle and can stop if the vehicle gets too close to the edge of the road.A reason why car crashes have different levels of injuries is that the force of impact varies in distinctive situations. The force of impact in accidents depends on the size, weight, and speed of the colliding
By not wearing a seat belt only the driver’s security is affected. First, Whenever a driver is not using his seat belt the protection of others on the road is not affected (Balaker 113). To clarify, There is simply no need to protect people from their poor decisions. Likewise, Laws should focus on protecting the
CRASH! You just got into an accident because you were on your phone and not paying attention,there is damage to your vehicle and theirs,guess what? You killed yourself by flying through the windshield and hitting them,basically turning into a flying projectile,all because you didn’t wear a seatbelt.
When people learn to drive sometimes it is hard to try and stop in time. Most people can do it but others have a tough time when they are not paying attention to what is going on around them. Braking distance is traveled before coming to a complete stop.
In addition, the stopping distance is longer considering the weight factor of the vehicle. Both these issues make this automobile very dangerous to the driver, passengers, other motorist, pedestrians, and small furry animals. On the other hand, the lower center of gravity that the car has to offer makes this vehicle less likely to roll over. There is also a shorter stopping distance for the car considering the weight of the car is much lighter.
Basically the higher the speed of a vehicle, the more difficult collision avoidance becomes and the greater the damage if a collision does occur.
