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.

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

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.

Word Definition Unit
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
Newton’s per kilogram
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

Be safe!

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
