Abstract
Rotational dynamics is the study of the many angular equivalents that exist for vector dynamics, and how they relate to one another. Rotational dynamics lets us view and consider a completely new set of physical applications including those that involve rotational motion. The purpose of this experiment is to investigate the rotational concepts of vector dynamics, and study the relationship between the two quantities by using an Atwood machine, that contains two different masses attached. We used the height (0.824m) of the Atwood machine, and the average time (2.15 s) the heavier weight took to hit the bottom, to calculate the acceleration (0.36 m/s^2) of the Atwood machine.
Once the acceleration was obtained, we used it to find the angular acceleration or alpha (2.12 rad/s^2) and moment of force(torque) of the Atwood machine, in which then we were finally able to calculate the moment of inertia for the Atwood machine. In comparing rotational dynamics and linear dynamics to vector dynamics, it varied in the fact that linear dynamics happens only in one direction, while rotational dynamics happens in many different directions, while they are both examples of vector dynamics.

Introduction
The experiment deals with the Rotational Dynamics of an object or the circular motion (rotation) of an object around its axis. Vector dynamics, includes both Rotational and Linear dynamics, which studies how the forces and torques of an object, affect the motion of it. Dynamics is related to Newton’s second law of motion, which states that the acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the
