Let a vector expressed in the inertial (Earth) frame be denoted as $\vec{x}$, and in a body-reference frame $\vec{x}_b$. For the moment, we assume that the origins of these frames are coincident, but that the body frame has a different angular orientation. WebA reference frame is a like a fixed point. Properties of other objects such as: position, velocity etc. are measured using the point. It is so because no point in the universe is stationary or static. Every point is moving depending on another 'so called' static point. See it like this: you are going to a amusement park in a bus with your friend. heilen streptokokken von alleine
