Question 1

Define and describe rotational inertia

Answer 1

> rotational inertia - resistance to rotary motion
depends jointly on two factors: body’s mass and distribution of this mass
more mass body has, greater it rotational inertia
rotational inertia reduced by concentrating mass near rotational axis
mass near center; less rotational inertia
mass near rim; greater rotational inertia
