For planar motion, the military tank can be thought of as twodistinct reference frames – the chassis reference frame and the turret/barrel reference frame.Students can relate to these two distinct reference frames because they already know theindependent motion of the turret with respect to the chassis. If the chassis (reference frame N)remains fixed to the ground and does not rotate but the turret (reference frame T) is free to rotate,the relative motion of two points, P and Q on the turret can be discussed (Figure 4). By fixingthe chassis of the tank to the ground, we can establish a

Other participants said that their coworkerswere too busy or too new to the work group to provide much help. Q: Did your [coworker] give you this assignment? A: Yes. Q: I assume he gave you background information? A: Yes and no. We both were new to this [name] system, so we pretty much were on the same page in terms of understanding the system.
