Physics Question- Rotational Kinetic Energy?

For linear motion we have the concept of Mass. F= MA but for rotational motion the geometrical shape and distribution of mass in the object have to be accounted for to get "rotational moment of Inertia or the first moment, I , the integral of m* r for each element of the object I think we then divide by total M but I am not sure. Its been 50 years since I got may BS degree.

There can be higher moments. Such as r^2 * m and the zero moment. Total M the first moment is center of mass.

R * m summed . Positive and negative r cancel to give the Center of mass ( aka center of gravity). Most physics problems of motion are reduced to the motion of the CM lets to learn.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
