Q
Relating Angular and Linear Quantities
A
- To describe the motion of a rotating object as a whole, all you need are the values of its angular position (q), angular velocity(w), and angular acceleration (a).
- If you are interested only in the motion of a particular part of a rotating object, you can convert from angular to linear variables using these formulas:; ; ; .
- The total linear acceleration is the vector sum of the centripetal acceleration (ac) and tangential acceleration (at)
