Normal Tangential/Polar coordinates

They constantly change direction

The normal tangential coordinate system is not a constant vector because____

0

In rectilinear motion, a(n) =

Omega theorem

Time derivative of a vector constant in magnitude but whose direction changes as a result of rotation is simply the cross product of the angular velocity with the vector

R(dot)
