Motion+-Vehicle+Safety

__MOTION AND VEHICLE SAFETY__
== In this topic you will investigate some of the fundamental principles involved in the movement of objects, in particular how objects influence and are influenced by the world around them. In particular you will look at Isaac Newton's Laws of motion and investigate how modern devices protect individuals in modern vehicles in terms of their motion. ==

** You need to be able to demonstrate an understanding of some of the fundamental aspects of moving objects, such as fiction, speed, velocity, mass and the interrelationships between them. **
==** To better understand the motion of objects we must know a little about some basic measurements that apply to objects and the way they move. These activities will give you information about mass, weight, speed, acceleration and other measurements allowing us to calculate and describe motion. Two activities are practical involving data collection and speed analysis. **==

__TICKERTIMERS - MEASURING SPEED IN THE LAB__
==A Tickertimer is a device which allows us the determine the speed of an object in the classroom. The Tickertimer vibrates at a constant speed (50 times a second or once every .02 seconds.) As the tape passes through the device dots are left allowing us to measure distance. Knowing bothe time and distance we can then calculate speed and acceleration.==

The documents below guide you through the excercise and analysis of the tapes. The video is a helpful demonstration

 * __ NEWTONS LAWS - INQUIRY RESEARCH __**

Find out about Sir Isaac and his Laws from the site below, then send an overview of Newton's Laws, with examples, to your teacher via email. ** ASSESMENT. Remember to print off a copy to place into your workbook. **

The following videos should help you understand Newton's Laws further

**The aim of this section is to allow you to learn about and: Demonstrate an understanding of the basic safety features of modern vehicles and your skills in using ITC (computer technologies) to researching and presentation of information.**
 * Demonstrate your ability to research a chronological development of Vehicle Safety features and present this information in an appropriate way.**

The video here is accesible at College only and is to get you to start thinking about the forces involved in car crashes and how these forces may be reduced to people might survive or be injured less. Watch the video and respond to the questions on the following sheet then hand it in. for **ASSESSMENT**

On a computer open the 'Clickview' program and do a search for the video 'Physics of car crashes' you will need your headphones.



This Video show a Small car involved in Crash testing and the effect of some safety devices.
