## Updating Resources

I never have sorted out these resources, so with our Third Roads Policing Inspector in the last 5 years, it is time for a sort out. Welcome aboard Inspector McHallum.

• speed is the main cause of accidents in the UK
• safety features and the Euro ncap system
• Average speed and average speed cameras
• Instantaneous speed and instantaneous speed cameras
• reaction time and the causes of reduced reaction time
• braking distance and the causes of increased braking distance
• estimating stopping distances, should I run out in front of that car?

We then coverdisplacement and velocity briefly and it is to try to get across why we don’t STD in Physics like they do in maths, but why we vdt, and vst!

• what is displacement?
• How is displacement different from distance?
• scalars and vectors
• velocity = displacement/time

Need to Know sheet

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?

I think these notes need a bit of an update, so here goes

## S3 Transport Resources

Covering Acceleration, velocity-time graphs, Newton’s Laws, Tart Ma Kart, Be a Road Crash Investigator.

• Crumple zones
• Crash Investigation

### 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.

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.

## Tart Ma Cart

This is the start of the Tart Ma Cart material put together by Gregor Steele from SSERC and spread by Brian Redman. Thanks guys.

The pupil instructions are given in the sheet and are copied below.

Style and Safety

You have probably seen TV shows where an ordinary car is fitted with an amazing body kit and a fancy stereo before being given a stunning paint job.

• Your group’s task is to take an ordinary physics trolley and fit it with a bumper or crumple zone to make it safer in a collision. You can make it stylish, but safety is more important!
• You will be given a choice of materials plus card and sticky tape.
• Your design must be able to be fixed to the front of the test trolley with Blu-Tac.
• It should not add more than 2 cm to the length of your trolley.
• It must not have a large effect on the performance of the trolley.
• Your design will be tested. The test will measure the deceleration of the vehicle in a head-on collision.

Do you think a large or small deceleration will be best in a collision? (Should the change of speed in the collision happen quickly or slowly?)
