Also, there have been a couple of things that have scared me. Two, actually.
Maths and physics.
I won't go into the maths bit now. It's kinda under my belt until next year again now, with a B1 for my written assignment, although my subject knowledge remains a bit iffy...
Physics was never a strong point for me either and I dropped the subject before 'O' level, in the days when science was still a 3-part subject, carrying on with both biology and chemistry.
Our follow-on task for our forces lecture was to make a marble run. I did a bit of research (read, looked at some toys) on the internet and working in a group of 4, we came up with this:
It's amazing what you can do with a bit of foamboard, some sticky pads, elastic bands and other bits salvaged from broken toys.
The Bounce at the end caused a HUGE amount of excitement, let me tell you. HUGE! That marble just BOUNCED into the pot every time!
Forces? Gravity? Friction? Resistance? Velocity? Acceleration? Deceleration?
