In this lesson the professor study the kinematics of the **rigid body**, it explain that the motion of the **rigid body** can be describe with six degree of freedom, three degrees for the position of the **center of mass** and the other three for the rotation of the body around the center of mass. Then the most general motion of theĀ **rigid body** is described as the sum of a translation of the **center of mass** plus a rotation and as translation have been already studied in previous lessons he focused in the rotational motion. For this purpose he introduces theĀ **Eulerian angles** and the **rotation matrix** and derive the **Euler's equations** of motion. Then he study the **Infinitesimal rotations** and the rate of change of a vector obtaining the **Coriolis** and the **centrifugal** forces. In this lesson he give the homework number 4 (Homework.4)

Dynamics of Rigid Bodies Part IIn this lesson of the Yale university the professor begins with examining rotation of rigid bodies in two dimensions. The concepts of "rotation" and "translation" are explained. The use of radians is introduced. Angular velocity, angular momentum, angular acceleration, torque and inertia are also discussed. Finally, the Parallel Axis Theorem is expounded.
