Physics Practicals are Ph*cking Phun~!

Says wayne and uni.

Then we stepped into the physics lab, to await our fates while destiny unfolds. Staring back at us, were lenses, 3 metre rules, a marble (glass sphere) and a stopwatch. Everybody thoughts were in unison, with the exact same meaning:

Lazy Mdm Shariffa was, now screwed we will be.

It took a 40% failure rate for practicals for her to re-run practicals THEORETICALLY with us, and for O levels, no THEORETICAL practical part came out, genius, excellento, which in german context, means you are screwed.

Let me give you guys the ans i got from my friends who got them from their teachers:

Focal Length: 14cm (allowance is probably + - 2.0cm like in chem)

Acceleration of Marble: 20~40 (not sure), but acceleration due to gravity is 10m/s^2, which is 1000cm/s^2, throw in resistance and friction, i'm sure a 40/1000, 4% efficiency rate is really horrendously scary.

Graph: Supposedly a curve

Ah well, it all boils down to practise makes perfect.
