THERMO Spoken Here! ~ J. Pohl © ( A4339~3/15) | ( A4340 - 1.17 Vector Notations) |
Typical vectors for a BODY (as system) are its spatial properties: position and velocity (also acceleration). The gravity force and sum of surface (or external) forces, ΣF, are vectors. The figure shows a BODY in 0XZ-space with a notation for its vectors.
Details of the figure are:
Beginners might think there is too much notation. Sketches that retain the physicality of physical situations require careful, consistent graphical notation. Notations are learned not so much for simple problems; they are learned as preparation to understand and solve more difficult problems.
