Physics Tips 2008(SPM Final Revision)

Physics Tips SPM 2008
From: Mr.Nava.S Desk

1.Measurement- Vernier Calipers/Micrometer

2.Impulsive force/Impulse-Try SBP questions (egg or watermelon drops from a table/2 objects collide from different directions)

3.Gas Law(Boyle’s/Charles) & Pressure in Liquid – Try questions on air bubble/Load on piston/Gas pressure related to a barometer

4.Hooke’s Law – pls know that area under this graph gives u work done=elastic potential energy

5.Bernoulli Principle – anything that in shape of aerofoil follows this law eg: curtain /tent

6.Archimedes Principle – Try questions involving boat and hot air balloon
7.Heat(SHC & Latent Heat)/Thermal Equilibrium

8.Snell’s Exp to determine value of critical angle using semi-circular glass block

9.Work,Energy,Power – Try question on Conservations of energy especially K.E and P.E

10.Youngs Exp.- both light and sound/ speed or water waves interference(nodal&antinodal)

11.Free Fall exp.

12.Convex Lens Magnification & Microscope/ Projector

13.Ohm’s Law – Learn simple calculations/gradient of graph V-R/Constant wire length and – resistance/ohmic and non ohmic conductor

14.Equilbrium of forces – car on slope/ anything tied to a string
15. Faraday/Lenz law/Motor – turning effect(Fleming Left Hand Rule)/relay circuit

16.Radioactive – chain reaction/simple calculations E=mc2/equations/half life calculation/nuclear reactor

17.Transistor exp. / Graph of Ib and Ic

18.Logic gates – don’t be sad u got to know all the gates before u can even try this !

If u have more time try doin questions on friction compensated trolley on a slope attached to ticker timer + kinematic calculations(car brakes on a rainy day) and Pascal principle ok !
Good Luck and Have A Great Day !

Remember Your Facts "Right"!

Good Luck !

Good luck and all the best to all those sitting for SPM on tuesday.
May god bless all of u.
Be confident and be focused when answering questions.

Biar besemangat bila menjawab soalan k.
