Relative acceleration of rigid links summary

The video tutorial explains angular velocity (Omega) and angular acceleration (Alpha) in the context of two points, A and B, on a rigid body. It discusses the relationship between the accelerations of these points, simplifying the formula by considering the constant distance (R) between them. The tutorial further breaks down the acceleration of A relative to B into tangential and normal components, providing formulas for each. Finally, it defines the terms and units used, such as R in meters, Omega in radians per second, and Alpha in radians per second squared.
