Not inertial frames
- Rotating reference frames are not inertial frames, as to keep something rotating (and thus change the direction of the linear velocity) requires the application of a net force.

A rotating frame of reference is a special case of a non-inertial reference frame that is rotating relative to an inertial reference frame. An everyday example of a rotating reference frame is the surface of the Earth .

Now let S be an inertial frame and S0 be a frame rotating with angular velocity ! with respect to S. Let {e 1,e 2,e 3} be a basis for S and {e0 1,e 0 2,e 0 3} a basis for S0. Let a be any vector — not necessarily fixed in either S or S 0— with components a i and a i respectively, i.e., a = a 1e 1 +a 2e 2 +a 3e 3 = a 0 1 e 0 1 +a 0 2 e 0 2 ...

In classical physics and special relativity, an inertial frame of reference (also called inertial space, or Galilean reference frame) is a stationary or uniformly moving frame of reference.

The derivation of the Navier-Stokes equations is based on Newton's second law: It is assumed that the kinematics of a particle is determined by the particle's interaction with its physical environment. Every acceleration (change of velocity) is caused by an external force. If one eventually knows all relevant forces, the acceleration can be calcula...
Consider two cartesian coordinate system: One is inertial (inin) and the other one (rotrot) rotates with respect to the first one with constant angular velocity:Ω=dφdtΩ=dφdt(1)Without loss of generality, the zz-axes of both systems can be chosen to be aligned parallel to the axis of rotation. Then the relative orientation between the two coordinate...
The transformation matrix RR depends on the angle of rotation φ(t)φ(t) and contains the coordinates of the rotational unit vectors with respect to the inertial basis:R=([ˆxrot]in[ˆyrot]in[ˆzrot]in)=(cosφ−sinφ0sinφcosφ0001)R=([xrot]in[yrot]in[zrot]in)=⎛⎜⎝cosφ−sinφ0sinφcosφ0001⎞⎟⎠(5)(6)As it is characteristic for a rotation matrix,R−1=RTR−1=RT(7)sinc...
When the origins of the coordinates systems coincide, then the position vector →r→ris independent of the particular coordinate system, since it connects this common origin with a particle's location in space (which is also independent of the frame of reference).
Newton's second law, F = ma, is used to describe the motion of an object in response to an applied force, but that presumes that the observer is in a non-accelerating reference frame. The term "inertial frame" is commonly used to describe such a frame of reference.
the rotating frame is the same as the axis of the fixed frame, and the rotating frame rotates about the axis. The angular velocity of the rotating frame will therefore be of the form 𝜔( )=𝜔( ) . As indicated by the notation, 𝜔( ) may vary with time, but it may be constant.
