Question

A long point-object, mass = 1.0 kg, moves in a circular path at a radial distance = 0.5 m from the axis of rotation. What is the moment of inertia of the point mass? Give your answer 3 significant figures.

Answer 1

Answer:
`0.25\ kg-m^2`

Step-by-step explanation:

Given

mass of Point object
`m=1 kg`

Distance
`r=0.5 m`

Since mass is moving in circular path therefore every time mass is at distance of r from center .

Also Moment of Inertia tells about the distribution of mass over the given region with respect to center of mass.

Therefore
`I=mr^2`

`I=1* 0.5^2`

`I=0.25\ kg-m^2`
