Given Moment of Inertia = and Length = 20

Calculate Mass

##### The distance formula is denoted as follows:

Moment of Inertia = Mass x Length2

##### Rearranging the formula, we get:

 Mass  = Moment of Inertia Length2

##### Plug in Moment of Inertia of 400 and Length of 20

 Mass  = 400 202

 Mass  = 400 400

Mass = 1

### What 4 concepts are covered in the Moment of Inertia Calculator?

inertia
a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
length
the measurement or extent of something from end to end
mass
a physical quantity of matter in an object. Mass is measured in terms of the weight of a body.
moment of inertia
quantitative measure of the rotational inertia of a body
