1. The problem statement, all variables and given/known data Not a homework question, I just need clarification. I'm slightly confused on the different kinds of accelerations involved in a rotating body. I often see three types of acceleration: 1. radial 2. tangential 3. angular I'm assuming radial acceleration is the same as centripetal acceleration. So is tangential acceleration the same thing as the linear acceleration of the body being observed while angular acceleration is the acceleration of the rotation (which points in the same direction of the axis of rotation I believe)? Also when a question asks: What is the resultant acceleration of the rotating body, what am I solving for?
