Moment of Inertia

Question 1

What is moment of inertia

Answer 1

Moment of inertia is a resistance of a body to angular motion

Question 2

What are the 2 factors that affect moment of inertia

Answer 2

-Mass of the body:
-higher mass,higher M.O.I

-Distribution of mass from the axis of rotation:
-closer the mass is to the axis of rotation,lower M.O.I

Question 3

Why might a diver increase their M.O.I right before hitting the water

Answer 3

Allow them to slow down resulting in a more controlled entry into the water
