S3 Transport

Need to Know

Various Need to Know sheets have been made as we’ve both tried to put something together. Check with your teacher what you’ve managed to cover.

Drat and here is one I made earlier!

 

 

 

The first sheet is the brief version, the second one has more detail in it.

Don’t forget you can get more information and detail from the National 5 section of this website. GO to the PHYSICS NOTES link in the header and click on the DYNAMICS section. You can also answer some of the Compendium Questions and check the answers in the LO Answer section.

Below are the same files as above but as word versions

 

 

This information will help you revise for your assessment. We have not covered the sky diver or vectors at right angles this year.

TermMeaning
At rest not moving, the object is stationary. It is not the same word as pens and pencils which are stationery!
Average Speedthe distance of the whole journey divided by the time for the whole journey.
Braking Distancedistance the vehicle will travel as the brakes are applied.
Displacementhow 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.
Distanceis how far you have travelled. It is another name for length.
Dynamicsthe part of mechanics dealing with Forces.
Instantaneous Speedthe speed at which you are travelling over a very short distance.
KinematicsKinematics means the part of mechanics dealing with motion, speed, acceleration etc
MechanicsMechanics 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.
ScalarA quantity that is fully described by a value and unit
Speed is the distance travelled in unit time.
Stopping Distancestopping distance= thinking distance + braking distance .
Thinking distanceis the distance a vehicle will travel in the time it takes you to react to the situation.
TimeTime- 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 Speedwhen your speed isn’t changing, it remains constant.
VectorA quantity that is fully described by a value, unit and direction
Velocitydisplacement 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!

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

https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/848485/road-casualties-year-ending-june-2019.pdf

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

  1. a) On which roads do most road deaths occur?
  2. b) Which group of road user have the highest death toll?
  3. c) Which part of Great Britain has the highest injuries and why?
  4. d) Why are most deaths on roads with speed limits of 21-30 mph?
  5. 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.

https://www.driving-school-beckenham.co.uk/mocktheory5.html

Road and traffic signs 2

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.

Glossary

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
