|---|---|
| Rigid bodies | Since an object moving at constant velocity is at rest in some inertial reference frame we need only consider conditions for static equilibrium. In static equilibrium an object must satisfy the conditions for both translational and rotational equilibrium. |
What you learn in Theory:
A rigid body is in equilibrium if it is at rest in an inertial reference frame.
What you learn in Practice:
A body at rest in the inertial reference frame of the earth is said to be in static equilibrium.
