In rotational kinematics equations, what quantity is analogous to force in linear kinematics equations?

What is the rotational equivalent of mass?

A boot is put in a stick which is attached to a rotor. The rotor turns with an angular velocity of . What is the linear velocity of the boot?

A particle is moving at constant speed in a straight line past a fixed point in space, c. How does the angular momentum of the particle about the fixed point in space change as the particle moves from point a to point b?
