Torque and Torque Arms
Rotational Force (AKA Torque) is a push or pull that attempts to change the rotation of an object.
T=F*r -> Where F is the perpendicular force to the radius of the torque arm and r is the radius of the torque arm.
Center of Mass - a point representing the mean position of the matter in a body or system
Hang Test - hanging an object from two points and drawing lines to find where they intersect will help you find the center of mass.

Linear vs. Rotational Kinematics
Linear Rotational
a = (v final - v initial)/∆t
v final^2 = v initial^2 + 2a∆x
∆x = v initial ∆t + 1/2a ∆t
v final^2 = v initial^2 + 2a∆x
∆x = v initial ∆t + 1/2a ∆t
