Some of you have lost the sheets (for the homework that was due today), and don’t know where to find them! Print them at home, and bring them from home, dragging your tails behind you! (By B Peep)
These are not all the UK road signs and there have been a few new ones over the years. I have attached pdf files of the ones you ought to know.
Remember signs in red circles give mandatory tasks (things you have to do)
Signs in red triangles are warnings
Here is the start of the TRANSPORT materials for lower school. You could choose to use this as an applications based upper school science course.
I have uploaded the powerpoint presentations and the corresponding pdf versions. Please note most of these files are very big! The file we are working on is highlighted in red.

Below are a set of resources for use with various parts of the Road Safety Topic. All these documents are currently in word format. Eventually I will upload pdf copies too. They are not necessarily in order- sorry.
We mentioned using the calculator to convert hours and minutes to decimals. You can find the link here. Using your calculator

holiday competition instructions Pupils find their average speed for a journey they made during the holidays. Issue prior to the holidays
Finding the Area Here is an exercise for students who might find it difficult to find the area under a v-t graph
Casualties grouptask This task might be a good starter for National 5 Assignments
Physics of Road signs Linking Physics with Road Signs, to introduce how Road Safety is all about Physics. This makes a good starter homework. The answers aren’t fixed and can be a great discussion opportunity.
MEASURING REACTION TIME Some ideas on how to find the reaction time of students, including some great websites. If you have a FIFEX reaction timer they make great practicals too.
Here are three links to reaction time games
sheep reaction.swf read-your-signals/game-reaction-time
This excel spreadsheet will allow you to find your reaction times from a dropping ruler. Just enter the drop distances in the yellow boxes and excel does the rest. Don’t forget to write down the values it gives you.
Speed TASK Mat 1 Using playmats find the speed of a car.
Speed TASK Mat 2 A different type of playmat.
The Post Office van An example of speed distance time, and also can be used for displacement and velocity.
vdt problems A dominoes game to practice speed, distance and time. Use as a homework
vdt problem answers The answers to the dominoes above.

Causes of Road Accidents. Research the reasons why the number of road accidents Causes of Road Traffic Accidents
|Acceleration||Is the change in speed in one second. . An unbalanced force causes acceleration or deceleration.||Usually this is measured in m/s2 but can be measured in mph/s|
|Air Resistance||It is the force that slows things down when they are moving through air.|
|At rest||we use this term to mean not moving. We can also say the object is stationary.|
|Average speed||found by timing how long it takes a vehicle to travel a known distance. Distance travelled per second.||measured in m/s|
|Balanced forces||When two equal forces are acting on an object in opposite directions and cancel each other out|
|Chemical energy||A store of energy in the form of a chemical, eg fuel for cars and food|
|construction||how something is made|
|Deceleration||The decrease in speed in one second. Something slowing down. This should be represented by NEGATIVE ACCELERATION||metres per second squared (m/s2) or ONLY in Transport mph/s|
|Displacement||how far you have travelled in a straight line. We would say “as the crow flies”||It is measured in metres or miles but must also have a direction. eg 10m north, 20 miles to the left.|
|Distance||how far you have travelled. It is another name for length.||It is measured in metres or during our road safety topic miles.|
|Dynamics||The mechanics part dealing with Forces|
|Effects of a Force||A force can change an objects speed, shape and direction.|
|Energy||Can be changed from one form into another form but cannot be created or destroyed|
|Force||A push or a pull. Has the symbol F and is measured in Newtons (N).||Newton|
|Force of gravity||Another name for weight||Newton|
|Friction||Is a force that can oppose the motion of a body.||Newton|
|Gravitational field strength||It is the force of gravity or weight acting on every kilogram. The weight per unit mass||
|Gravitational potential energy||The work done against gravity||Joule|
|Gravity||A phenomena that causes objects to fall down, BE CAREFUL HOW YOU USE THIS TERM and where possible try to avoid it.|
|Heat energy||The energy produced when objects are slowed down by friction.||Joule|
|Heat energy||The internal energy of an object. Heat may be defined as energy in transit from a high temperature object to a lower temperature object.||Joule|
|Hookes Law||This law states that providing you don’t overstretch a spring the stretch or extension of a spring will double if the force on the spring is doubled.|
|Instantaneous speed||is the speed at which you are travelling over a very short distance.||It is measured in metres per second or miles per hour.|
|Instantaneous speed||The speed at one particular point in time (and can be very different from the average speed). It is the same as average speed if journey time is very small or if the object is traveling at a constant speed.||m/s|
|Kinematics||Mechanics dealing with motion, speed, acceleration etc|
|Kinetic energy||Symbol Ek Is the energy an object has because it is moving. The higher the speed the greater will be it’s kinetic energy||Joule|
|maintenance||the care or upkeep of a mechanical object|
|Mass||The amount of matter in an object and is measured in kilograms.||kilogram|
|Mechanics||The branch of Physics dealing with motion (how things move).|
|Momentum||The product of mass and velocity. A quantity that only moving objects possess.|
|Newton balance||Is used to measure force (a spring balance)|
|Newtons First Law||States that an object remains at rest or continues in the same direction at the same speed, unless there is an unbalanced force acting|
|Newtons Second Law||States that F = m x a|
|Potential energy||A store of energy||Joule|
|Reaction Force||A force pushing in the opposite direction to the action force eg, a gun fires a bullet, the gun places as action force on the bullet but the bullet places a REACTION force on the gun.||Newton|
|Reaction Time||The time it takes our brain to process information that something has changed, or a danger has occurred.||second|
|Resultant force||A force can change an objects speed, shape and direction.||Newton|
|Scalar||A quantity that is fully described by a value and unit|
|Speed||how far you travel every second.||In the lab our distances are measured in metres and our time is measured in seconds so our units of speed would be metres per second.|
|Speed||is the distance travelled in unit time.||In road safety we look at miles travelled every hour or miles per hour.|
|Stationary||we use this term to mean not moving. We can also say the object is at rest.|
|Time||how long your journey took.||It is measured in seconds or during our road safety topic hours.|
|Uniform Speed||When your speed is uniform we mean that your speed isn’t changing. It remains constant.|
|Upthrust||It is the force that pushes things up in water.|
|Vector||A quantity that is fully described by a value, a direction and unit.|
|Vehicle||A thing used for transporting people or goods, esp. on land, such as a car, truck, or cart.|
|Weight||It is the force of gravity pulling an object down and is measured in Newtons|
|Work done||Is a measure of the energy transferred when a force moves through a distance. Work done = force x distance in the direction of force|
Safety saves sickness, suffering, sadness. ~Safety saying, circa early 1900s
Practice “Safety First” to-day: It may be too late to-morrow. ~Safety saying, circa early 1900s
Do not depend on others for safety — Help yourself. ~Safety saying, circa early 1900s
Every accident is a notice that something is wrong with men, methods, or material — investigate — then act. ~Safety saying, circa early 1900s
