My guesses for some 6 markers:

- Evaluating car safety methods (e.g. seat belts, crumple zones, side impact bars) and how they work
- Evaluating different types of circuit breakers (e.g. RCCBs)
- Evaluating uses of radioactivity in industry (e.g. testing thickness of foil)
- Explaining nuclear fission (e.g. chain reaction, neutron collision, splitting of nucleus)

It's definitely not going to be on Terminal Velocity, as that came up in June 2012 nor anything at all to do with stars as that came up in both the Specimen and January 2013, for both starts smaller than the sun and greater than the size of the sun. These may come up as lower mark questions though.

im definitely screwed if those should come up as 6 markers! :eek:

Forgot all about crumple zones :s-smilie:

Time to revise it...

So say if the car safety features question came up as a six marker, would you mention these points:
They have crumple zones and side impact forces which fold up during a colission to increase the impact time to reduce the force. They have seatbelts and airbags which spreads the force on the body over a larger area. The seatbelts helps to reduce the force by increasing the impact time taken to hit the steering wheel. The airbags changes momentum slowly so the force is less than if it changed momentum quickly by hitting the steering wheel.
How many marks would that get me?

To be honest the mainpoints is that you've identified AIRBAGS,CRUMPLE ZONES, SEATBELTS (3) Explain them Increase Impact time reducing impact forces. (3) there is no markscheme for 6 markers. They have suggested answers

As you can tell it would not be about cars that would be 2 or 3 mark q's (not much to talk about), it would be about making your own investigation about proportionality or something like that.
