We looked at rotational moment and the moment of inertial as well as some connected ideas.

The Greek letter omega stands for angular velocity, alpha stands for angular acceleration. Capital L stands for angular momentum. Capital T stands for the period.

Focused some time on algebraic manipulation of equations, especially with reciprocals and ways to simplify the equations.

It would help to write notes about what the teacher is saying for some problems rather than just what is on the board.

The ‘moment of inertia’, for which we use the capital letter I is basically how difficult it is to rotate something. Similar to mass in that it takes more force to accelerate a larger mass, it takes more torque to accelerate something in an angular way. It does not have to do with ‘a moment in time’.
