all chapters all formula
Work Energy and Power.
1-W=(F cos theta) S.2-W=FS.3-1erg=1dyne ×1cm.4-W=FS cos theta=FS.5-F=mg.6-W=FS=mg.7-W=mg.8-Power=Work/Time.9-Power=force×average velocity.10- KW= 10to the power 3W.

Density is mass per unit volume
Density= mass/volume
Velocity=displacement/time
Force=rate of change of momentum
Momentum=mass×velocity
Power is rate of work done
Power=work/time
Unit of power is watt
Potential energy(P)
PE=m×n×g
m=mass
g=acceleration due to gravity
h=height
Gravity(Force due to gravity)
Fg=Force of attraction
G=Gravitational constant
M1=mass of first object
M2=mass of second object
Fg=G×M1×M2/r2
Index of refraction,
n=c/v
c=velocity of light in vacuum
v=velocity of light in given material
