# Telemetry in motor racing ideas in context?

Hi does anyone have a revision list for the ideas in context Telemetry in motor racing? I'm really stuck with what exactly to revise, my teacher didn't give me anything and I'm struggling to find anything useful on the internet.
Thanks

We were given a list of questions related to telemetry. If you can't answer some of the questions, just let me know and i'll give you the answers

1) Why is data transmitted to engineers in the pit lane?

2) Name the parts of the electromagnetic spectrum in order of increasing wavelength

3) Why does telemetry use microwaves and radio waves to transmit data as opposed to visible light or ultraviolet?

4) Give another use for radio waves and microwaves

5) Using diagrams and full sentences, explain the differences between analogue and digital signals

6) Draw the signal traces for analogue and digital signals

7) Give 2 reasons why some Formula 1 teams have switched from analogue to digital systems for their radio connection with the racing driver

8) How does time taken to stop affect the force acting on the object that is stopping?

9) How does a seat belt work as a safety feature?

10) How do crumple zones help reduce the force acting on the driver in a crash?

11)Describe and explain at least 2 ways that the HANS device helps reduce damage to the driver in a crash

12) Why is the forehead better suited than the top of the spine to taking the force during an impact?

Hope this helps!!

also revise how to use the equations like:

Kinetic energy = 1/2 x mass x velocity squared

Momentum = mass x velocity

Change in momentum = resultant force x time

Wave speed = frequency x wavelength

Speed = distance / time

In addition, look at wave modulation as my teacher thinks that could come up and distance time graphs

Hope this helps :)

Please may i have the answers to check over my work? thank you very much this really helped!

And another thing!! how analogue is converted to digital (and then back to analogue) :)

why not have a look at p4 qnd p6 revision as these topics are covered in those units : )
