Natural Forces Affecting The Driver Essay

After starting the red car, mark the position, in front of the car for every second. Stop the car after having 10 positions marked.

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 do not know how stable the surface is that your car is on, so put on your parking brake to prevent the car from moving for now. Just remember to take

One massive factor that has a massive influence on the braking distance is the weather. After a rain when the water is sitting on the road cars can’t obtain traction and this is known as hydroplaning. Therefore the braking distance will be a lot longer compared to if it was in dry weather. Another major factor is the surface that the car is travelling on as well as the gradient. For example a roads made of either asphalt or bitumen are going to allow the car to stop quicker than if it was travelling on a dirt road. Other factors include the condition of the car tyres as new tires which are in good condition are going to gain more friction compared to bald tires. Lastly the quality of the brakes will have a massive impact as worn ones won’t be as effective then better quality

Newton’s law of inertia states that an object in motion will stay in motion until an equal and opposite force stops it. In a collision, a driver’s car is stopped by another object (Ex: another car, a tree, a lamp post). Anything not attached to the car will continue to move forward because they are not stopped by the force that halted the car. Therefore a person who is not wearing a seatbelt during a collision would fly to the front of the car until they hit something (Ex: the dashboard, the wheel, a car seat).The stopping distance of the vehicle going 60 mph would be four times greater than that of the vehicle going 30 mph. This is because kinetic energy increases exponentially along with velocity. From my prior knowledge in physics, I know that the formula for

3. For the same Kinetic Energy the stopping distance of a small vehicle will be less than the larger vehicle due to the conversion of inertia.

While your car structure is crumpling to take on the force of the crash, the people and items in the vehicle still have kinetic energy as well. This means that your car will lose energy and stop moving, but your body will still be flying through space. Seatbelts will stop your body from moving, but your head will keep moving forward. In severe accidents, this can cause your head to slam into the windshield or steering wheel. To prevent this from happening, airbags are used to slow down the momentum of your head. As your head hits the airbag, the nylon bag deflates so that your head does not end up bouncing back into the seat. If you were recently in a car accident and this did not occur, you should contact a Houston auto wreck attorney to talk about your

Because there is no energy left to push the cars back they just collide and stay there, cars can possibly have stronger hulls, better airbags or more airbags on the side doors, doors that can resist more to have a better chance to open upon collision. They are things that can be put into the car to make it resist more force but not make it completely negate it. Devices that can help the car to detect when a collision is most likely to happen and do something to try and avoid or reduce the effects, Auto Emergency braking (AEB), forward collision warning, electronic stability control and more to help precent

If you have ever driven on an unmarked highway, you no doubt noticed that it was often difficult to judge the position of your own vehicle. Whether a car was approaching toward you or passing you, you may have experienced a moment of uncertainty while you tried to determine the path of the other vehicles and decide whether you were infringing on their space. Unmarked pavements create distractions for drivers, making travel more hazardous for themselves and everyone else who is on the same road.

Most car safety devices in the modern day use overwhelming amounts of physics background in order for these devices to be as efficient as they are. Included concepts include inertia, momentum, force and acceleration.

The first is how far the car travels when the driver is reacting and braking (Transport for NSW, n.d.). As the speed of the car increases, the distance travelled between seeing an obstruction and pressing the brakes does too. The car’s inertia means that an increased speed requires a greater distance to brake to a complete stop. These mean that a car might still be travelling at high speeds upon impact (NSW Centre for Road Safety, 2016). Figure 1 shows the relationship between speed and distance travelled when reacting and braking. The second concept influenced, is the amount of kinetic energy that has to be absorbed upon impact (Transport for NSW, n.d.). To calculate kinetic energy the equation KE = ½mv2 is used (The Physics Classroom, n.d.). Looking at this, the fact that the value for speed is squared shows how significant speed is on the resulting kinetic

When traveling in an unfamiliar area, make sure you know your exit number early on. Then you can anticipate when you will need to exit and avoid having to take the exit at the last second.

Sir Isaac Newton once stated, “I can calculate the motion of heavenly bodies, but not the madness of people,” referring to the ability to prevent accidents from occurring. Throughout my research paper, I will be discussing how the Newton’s Laws of Motion apply to automobiles. I believe this is an extremely interesting and relatable topic because we are at the age where we are beginning to drive without relying on our parents. Although some people may not currently be driving, we have friends or acquaintances who are able to do so and should be informed on how a collision happens and how it affects the vehicle. Additionally, adults nowadays are not serious about driving even though it’s a dangerous process, thus encouraging me to inform people on the subject. We should all be well aware on the issues concerning driving because we all have some sort of interaction with vehicles in our everyday lives. This interaction refers to being the driver of the automobile, the passenger, or the people walking around the vehicle.

Car crashes are most commonly caused by speeding. This is due to the time it takes for the driver to realise they need to engage the brakes, and the time required for the car to fully stop. This is known as the stopping distance. The stopping distance depends on two factors. Firstly, reaction distance, which is the time it takes for the driver to know that they need to brake. While this is happening the car continues to move. The average time it takes for a driver to react is 1.5 seconds. The second factor involved with stopping distance is the braking distance. Breaking distance is the distance it takes for the car to stop when the brakes are applied. If these factors are not carefully considered, it is likely a collision will occur. The outcome of a collision depends on the speed the car is going. The faster the car is going, the greater the damage and the passenger. Car crashes, stopping distance, and brakes all are significantly connected to the characteristics of motion ( British Broadcasting Corporation , 2014).
