In relationship to most experiments and observations the Earth is considered an unmoving object. When looking at things in a larger scale, it moves.
Any object can be used as the reference. There's no such thing as an 'unmoving' object. It's only unmoving relative to itself or to other things that are moving exactly the same as the object. That's the whole reason that you need a reference point.
An unmoving object needs a force to be applied to it in order to start moving. This force can come from an external source like a push or pull, or from internal sources like stored energy or tension.
Static electricity involves electric charges that remain unmoving on an object. These charges build up when two objects rub against each other, transferring electrons and creating an imbalance of positive and negative charges.
Stationary is a word that means still and unmoving.
still
slow
Immobile
Maybe unmoving, or sedentary.
Unmoving, immobile.
Unmoving, resolute, unchanging
Earth pulls on the object, and the object pulls on Earth
For an object to stay in place - unmoving - two conditions must be fulfilled:* The sum of all forces on the object must be zero. * The sum of all torques on the object must be zero. Usually the forces that tend to keep an object in place (despite forces such as gravity or wind) are anything holding it fast in place - including friction.
