These are highly detailed that I complied over two years of studying this subject. Since I took notes like crazy, no area is left untouched so everything is there if you are struggling to understand a concept or equation. They are colourful, organised and neat, so perfect for the eye to understand.

Periodic Motion

, Simple Harmonic Motion

The acceleration and resultant
force of body is proportional to

a

its displacement from its equalibrium position .

The acceleration and resultant
force acts towards equilibrium position.

REMEMBER :
r acceleration
Force are both vectors so have size a
