Density
The below video will help give more insight in the topic of density
with examples and help build understanding for the numericals.
• Density is a measure of mass per unit of volume.
• The average density of an object equals its total mass
divided by its total volume.
• An object made from a comparatively dense material (such
as iron) will have less volume than an object of equal mass
made from some less dense substance (such as water)
• Perhaps the highest density known is reached in neutron
star matter.
• An object will float if it is less dense than the liquid it is
placed in, and an object will sink if it is denser than the
liquid it is placed in.
Density Numerical
• Formula is p = m / V, where p=density, m=mass, V=volume.
• The unit for density is usually g/cm , sometimes is also kg/m .
