A place where I do on line revision. I like to surf the Net a lot and decided to create a blog where I could do my revision anywhere, without my books.

Physics: Density
Density: mass per unit volume.
p = m/v
Where:
p = density (kg/m3 )
m = mass of object in kg
v = volume of object in
m3
SI unit of density = kg/m3
Substances that float on water has lower densities than water.
