Rotational Kinematics

We have now defined angle, angular velocity, and angular acceleration exactly in the same way we defined their linear analogus, displacement, velocity, and acceleration:

When we studied linear motion, we derived the "big three Kinematics Equations":

Since our definitions of the rotational quantities are identical to the definitions of the analogous linear quantities, we can immediately write down the same "big three Rotational Kinematics Equations":
