### S2 Lockerbie Academy Road Safety & Transport Notes from 2020

This is the 2020 version of the Speed topic notes and further down in this email I will add the work for covid19 for those who can’t get on Teams. If you read through the Learning Outcomes/ Need to know, you can find out what you need to know. There are loads of simulations and videos out there to help you.

Here is the updated materials

speed-distance-time word speed-distance-time pdf

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

The Post Office van word The Post Office van pdf

Stopping Distance word Stopping Distance pdf

REVISION OF TRANSPORT word REVISION OF TRANSPORT pdf

Velocity sheet 2018 word Velocity sheet 2018 pdf

For those without a protractor, you could print one off , it wont be great unless you could print on an acetate (clear) sheet, but it is better than nothing.

I really must update the route cards for the playmats as they really are dangerous! Must start in the car park!

Dominoes

Term | Meaning |
---|---|

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!

## Covid Work

### Work for after Easter

#### REVIEW

1. Review your work on Road Safety using the powerpoint and make sure you’ve answered the revision question quiz (Miss Horn uploaded)

#### NEW TASK

1. Watch the videos

https://www.youtube.com/watch?v=Xo3KBoEMDEo

https://www.youtube.com/watch?v=O22zcaELpaA

https://www.youtube.com/watch?v=hBbxznjLrL4&t=48s

2. Go slide 108 on the S2 SPEED powerpoint on DISPLACEMENT and VELOCITY

https://www.mrsphysics.co.uk/bge/s2-road-safety/s2-speed-2020-final-3/ work from slides 108- 124, you can do the practical if you have a playmat, car and timer

3. Complete the sheet on Displacement and Velocity https://www.mrsphysics.co.uk/bge/wp-content/uploads/2018/02/Velocity-sheet-2018.pdf.

4. Answer the Quiz on Displacement and Velocity in Teams.

#### ALTERNATIVE

5. OR complete a SPEEDING SURVEY https://www.mrsphysics.co.uk/bge/wp-content/uploads/2016/08/speed.pdf (page 6) Make a survey after asking your family and friends who drive, but remembering to keep your distance!

This will require some explaining so are you ready.

1) You are going to go for a walk, or run as part of your daily exercise.

2) Count the number of steps that you do and keep walking until you can see a direct and safe line to your home

3) Record the number of steps that you have taken.

4) When you can see a direct and safe line to your home or starting point stop, face home/ your starting point and walk directly to your starting point. If you have a compass look at the direction you are travelling in.

5) Record the number of steps that it took to get home.

6) The number of steps you took on the way out is your DISTANCE TRAVELLED, the number of steps back is your DISPLACEMENT.

7) Draw that as a sketch on your notes of paper.

8) Repeat this task but try to time how long it took you to walk out to the place where you stopped. Record the steps and the time it took to get there. This could be in seconds/ minutes/ hours or elephants (nearly seconds).

9) Walk back again counting the number of steps, but not timing it.

10) Speed = number of steps out/time to get there

11) Velocity = number of steps to get back/ time to get there and a direction.

12) Don’t forget to add you units even if this is in steps/elephant

13) Can you try to explain, Distance/ Displacement/ Speed and Velocity?

### First Week of Lockdown

Work through the Speed Powerpoint that will be on TEAMS and on https://www.mrsphysics.co.uk/bge/transport-2018/

Check the work on TEAMS and on here. We will set an online ASSESSMENT at the end of APRIL.

IN addition try some of the RESEARCH TASKS below

Do NOT complete the AIR BAG practical until the FULL RISK ASSESSMENT has been uploaded.

#### By the Easter Holidays you should have covered

- Road Safety and Road Signs
- Average Speed
- Instantaneous speed
- Reaction Time
- Thinking Distance, Braking Distance and Stopping distance

#### Research Tasks-

Take a note for your SALs Booklets

Welcome to the Lockerbie Academy Additional Work Sheet. Hopefully you’ll be working your way through the power point on TRANSPORT 1 -SPEED, which I am in the middle of updating.

There are plenty of speed distance time calculations you can do and I’ll add work on calculators.

Why don’t you make some suggestions about where Physics and Road Safety meet?

Choose 1 or more of the following 8 tasks to complete. Don’t complete the practical until I’ve uploaded the full risk assessment.

# 1. Road Safety Statistics

Are you bored already and need something to get your teeth into?

https://roadtraffic.dft.gov.uk/custom-downloads/road-accidents

Why don’t you select a group of road users, years, speed limits, type of road users, country, Region and research to see if you can find out some of the following

- a) On which roads do most road deaths occur?
- b) Which group of road user have the highest death toll?
- c) Which part of Great Britain has the highest injuries and why?
- d) Why are most deaths on roads with speed limits of 21-30 mph?
- e) Are there differences between male and female drivers? Are there enough details for you to say who is a safer driver?

Ask yourself some questions to answer

Make sure you try to show your results in a table, graph or pie chart. Why not have a play with EXCEL? I’ll try to update the Excel for 2016 a.s.a.p. but I’ve other things to do first.

# 2. Road Signs

How about trying to learn your road signs?

https://highwaycodetest.co.uk/road-traffic-signs/

If you can’t face doing 157 questions try some of these tests.

# 3. Reaction Time When Driving

If you are doing this task you’ll need to graph your results. Do your reactions improve as you play the game? Can you get the scores of your friends and plot data from you and your friends. Do older students have better reactions?

https://www.justpark.com/creative/reaction-time-test/

https://www.humanbenchmark.com/dashboard/reactiontime

# 4. SPEED SURVEY

I’ll upload the diagrams when I can get a better quality image.

# 5. DRIVER ALERTNESS / PERCEPTION

Will you be an alert driver? Can you spot and react to the hazards. Write a report about what you found out.

https://www.driving-test-success.com/theory-test-alertness/theory-test-alertness.htm

https://www.theory-test-online.co.uk/free-hazard-perception-test-demo.htm

Alertness study test (with hints)

# 6. Practice Excel

Can you plot this data in EXCEL in a graph? Make it a stacked graph. Search online for a better diagram.

# 7. Road Safety Analysis

Look at the road statistics below. State what you can see in the data and can you give reasons for the massive changes since 1964 in the numbers of road deaths, injuries and severe injuries.

# 8. AIR BAG PRACTICAL

If you have this material in the house you might want to try this, but you ought to wear googles and you MUST check with an adult before completing. You’ll need a tray underneath as this could make rather a big mess.
