S2 Lockerbie Academy Road Safety & Transport Notes from 2020
I’ve started on a total rewrite so try these first. I hope to complete them in the next few days. If you get ahead go back to the 2019 version
Here is the updated materials
Get some practice at speed distance and time questions
If the above are still a little too hard try the sheet below. Here I am not asking you to calculate speed distance or time, but can you extract the information from the sheet, write the equation and substitute?
To check out using your calculator try the following links, if you can’t face the whole of each video check out from the times I’ve given
Nice video on Using the Casio calculator, look at 12 mins in to the video!
or this one 3 mins 12 s in
I really must update the route cards for the playmats as they really are dangerous! Must start in the car park!
|At rest||not moving, the object is stationary. It is not the same word as pens and pencils which are stationery!|
|Average Speed||the distance of the whole journey divided by the time for the whole journey.|
|Braking Distance||distance the vehicle will travel as the brakes are applied.|
|Displacement||how far you have travelled in a straight line. We would say “as the crow flies” You must quote a direction when writing down a displacement.|
|Distance||is how far you have travelled. It is another name for length.|
|Dynamics||the part of mechanics dealing with Forces.|
|Instantaneous Speed||the speed at which you are travelling over a very short distance.|
|Kinematics||Kinematics means the part of mechanics dealing with motion, speed, acceleration etc|
|Mechanics||Mechanics is the branch of Physics dealing with motion (how things move)|
|Reaction Time||the time it takes a person to react to a situation and understand the dangers.|
|Scalar||A quantity that is fully described by a value and unit|
|Speed||is the distance travelled in unit time.|
|Stopping Distance||stopping distance= thinking distance + braking distance .|
|Thinking distance||is the distance a vehicle will travel in the time it takes you to react to the situation.|
|Time||Time- is how long your journey took. It is measured in seconds or during our road safety topic hours. We never write sec or secs in Physics to mean seconds|
|Uniform Speed||when your speed isn’t changing, it remains constant.|
|Vector||A quantity that is fully described by a value, unit and direction|
|Velocity||displacement covered during the journey divided by the time taken. You must quote a direction when writing down a velocity|
Are you really stuck on drawing that graph in your homework? Here is a hint!
