Physics Tips/KL

Hi guys....there is some physics tips for KL students...i think its from gombak...got it from a student
Hope it could help ......looks genuine:)

1)velocity-time graph
2)Bernoulli Principle
3)Pressure Law
4)Convex lens
5)Refraction (water)
6)Archimedes Principle
7)Transistor(Auto Switch)

Hey don't depend so much on tips until u don't study.
Good Luck

Tips for Trial/Physics

Dear selangor students...i'll get some tips for monday exam
Ill update on friday evening

Tip of the Day

Link this two principle : Archimedes Principle and Principle of Equilibrium of Forces

Answer : When an object is floating or hanging in a liquid the total force upwards and total force downwards is the same.

so if an object is floating :
bouyancy force = weight of the object

and if its hanging on a spring balance:
bouyancy force + tension on the spring = weight of the object
