Many people look at road safety as non-essential‚ but always there. What people don’t know is that everyday more than one hundred peopled are killed due to road safety‚ or lack thereof. Around six thousand people are injured or incalpacrated due to this (source1). Road safety is a very important issue; it effects most people’s lives. Whether they know it or not. Police officers have a key role in ebcouraging improved road-user behavior. The general deterrence provided by police and will promote

THE PHYSICS BEHIND CAR SAFETY FEATURES Cars contain several different types of safety features. These numerous safety features all have their own significance to the driver‚ as well as to the passengers. The purpose of this report is to show and express how physics is involved in automobile collisions and similarly how it is used to prevent injuries during accidents. Isaac Newton’s three laws of motion are used to describe the purpose of the three main safety features that cars are obliged to consist

Try to make the occupants change velocity in the same way as the car does An inertial-belt is used to keep the occupant moving at the same velocity as the car at all times therefore preventing them from moving with their own inertia and sharing it with the car.

This year in science‚ we were paired up in groups to build a car powered only by a rubber band. There was a lot of physics and thought put behind the planning of our car. The rubber band moved the car by storing up elastic potential energy which then turned into kinetic energy when released. Newton’s Laws of Motion also come in handy when thinking about how to keep the car moving. “An object in motion stays in motion.” There was also a lot of thought put into the wheels. We had to be aware of the

CAR SAFETY Active and Passive: Car safety features are grouped into two categories: Active and Passive. Active feature are designed to reduce the likelihood of a crash. Things such as tires‚ brakes‚ lights and steering are active features. The most important of all of them however is the driver. Passive safety features aim to reduce the damage done to a car ’s occupants in the event of a crash. These include things like seatbelts‚ airbags‚ and crumple zones. For all these features any car

Americans are hurt or killed in car accidents. Many factors can play into an accident. Road condition‚ mechanical failure‚ driver error‚ or simply an ’act of God’? Despite the countless reasons for a car accident‚ one factor is always present‚ no matter what the case: physics. Every accident that has ever occurred has involved physics. Using references found in the class text‚ in science journals‚ and on the Internet‚ I will prove this to you. Take‚ for example‚ two cars traveling in opposite directions

Toy cars have been played with by children for many years. Would one wonder the way a model or toy car rolls down a hill? One would think it would be because it has wheels‚ this is true but there is more to a car rolling downhill than it having wheels. Gravity is the force that is keeping all things on the ground. The heavier an object is the more gravity has an effect on its momentum. If you put a toy car on a downhill slope it will begin to roll because of gravity. The more the car weighs will

Introduction As cars and other motor vehicles get faster‚ they become more and more dangerous to use. While this is the case‚ there are many different methods that manufacturers have used to help prevent harm to their consumers. These methods include: air bags‚ seatbelts‚ antilock breaking systems and many more. These three features are by far the most commonly known safety features for cars‚ and pretty much any new car that is manufactured will have all three of these safety features‚ not only
