Relative Motion And Inertial Reference Frames.

4. Relative Motion And Inertial Reference Frames.

What relative motion is.

Relative motion and inertial reference frames. looking specifically at a point or mass on a rotation moving.

How a relative to point, changes the math's, but not reality.
What the observer can see is not always the reality for that object being observed. And never when on a rotation that is moving.

Watch all four of the videos.
Understand Rigid body rotation with translation, this is key.
