motion can be observed from any position
Motion is always relative to something. There's no such thing as really "stationary."Stationary only means that the motion of the observed object matches the observer's motion. Example: Reading the book that lies 'stationary' in your lap while you're in a car or on a passenger jet.
friction can not move stationary objects, it just opposes the relative motion between them.
Motion is calculated by comparing it to something else which may or may not be stationary. Hence you are measuring it's motion relative or in relation to the other object.
Movement Occurs When an Object moves Relative to a Stationary Object
Motion movement and changes
There is no such thing as a "stationary" object. Every motion is always measured relative to something else, which, coincidentally, is what the question is all about. The thing against which motion is measured is called the "reference frame".
refrence point is a point relative to which a motion can be observed
Examine the condition when two forces And
The bike. Even though you and the bike are in motion the positions do not change.
Objects that are "stationary" on Earth's surface are moving faster nearer the equator. The eastward motion of the rotating Earth is greatest at the equator (about 1037 mph or 1670 kph).

Motion is always measured for something in relation to something else. A car is travveling in relation to the road, but the steering wheel is stationary in relation to the dashboard.
