flukey-lukey Posted June 22, 2010 Share Posted June 22, 2010 Ok so this may seem really simple, but I'm just stuck for what to start writing... I've been studying impact forces and deceleration due to gravity etc etc blah blah and one of the questions is... "Explain any similarities between the helmet (pushbike/skateboard type) and a car airbag in providing safe deceleration" So, apart from the obvious 'they both buffer and reduce the impact force due to momentum and/or gravity' I'm a little lost for words. Its only worth 4 marks so don't want to spend too much time on it, but 4 marks usually means raise 4 points/issues. Any input from any boffs on here please?

flukey-lukey Posted June 22, 2010 Author Share Posted June 22, 2010 The difference in science to produce the same effect? hmmm isn't that more about the differences and not the similarities? Google HAS to be your best friend here, eh?! Tried that, not really getting a direct comparison to be able to find any similarities Quote Link to comment Share on other sites More sharing options...

Smallshinyant Posted June 22, 2010 Share Posted June 22, 2010 does they spread the force across a greater area. helmet: single point of impact spreads across area touching head. Buffered and collapsing http://cozybeehive.blogspot.com/2008/03/how-bicycle-helmet-works.html airbag: single point to an area of collapsing support against face and torso slowing the impact http://www.2carpros.com/how_does_it_work/airbags.htm all stuff you may know, just trying to help Quote Link to comment Share on other sites More sharing options...
flukey-lukey Posted June 22, 2010 Author Share Posted June 22, 2010 ahhh yes, interesting! I think this is what I'm after...
