# #23a   Frames of Reference: The Centrifugal Force

Uniformly moving frames of reference experience no new forces. Uniformly accelerating frames and rotating frames do so. If we want to express the equations of motion in their own frame of reference, we must always add "inertial forces" to represent the effects of their acceleration. The centrifugal force is one such force, described here and illustrated by examples.

on the board and in the notebook must be agreed on by the class.
In this lesson plan, all vector quantities will be underlined.
