The fan is un-balanced When you bought the fan, there was a package with it. In that package there was a device that looked like a plastic paper clip. This device is used to clip on to a blade to balance the fan and stop it from wobbling. It is sort of a trial and error method on placement of the clip but once the correct position is found it does the job very well.
A metallic bond has free electrons that can move around the metall atom lattice. Note that electrons never stop moving so all bonds involve constantly moving electrons, including ionic.
molecules in the air constantly moving and hitting the dust particle.
You can use a rake to collect leaves. It is a tool with a long handle and a row of projecting teeth for gathering and moving leaves and other debris.
If you see anything that appears to be moving, then you know that relative to that thing, you're moving. That's the best and only thing you can do, because there is no such thing as 'really' moving ... only moving relative to something.
Tectonic plates are large sections of Earth's crust that are constantly moving. These plates float on the semi-fluid asthenosphere layer underneath, causing them to shift and interact with each other at plate boundaries, leading to geological phenomena like earthquakes and volcanic activity.
Because human skin cells (the main constituent of dust) will cling to almost anything - whether it's moving or not ! Additionally, the motor driving the fan will have a minute static charge when running - which will attract dust particles.
i have black finned sharks and they chase each other constantly!! i wouldn't think anything of it being that sharks are very active aquarium animals and are constantly moving and playing.
The moth on the ceiling may not be moving because it is resting or sleeping. Moths are known to be inactive during the day and may stay still for long periods of time.
Some things that are constantly moving include particles in the air, oceans and rivers, tectonic plates, and celestial bodies in space.
Maybe you could go see if they need help with moving or building anything (if you want, this is only a suggestion), then you can see whats causing the bumping or dropping on your ceiling, you can also be making new friends this way and mention that you heard the sounds coming from your ceiling. Good Luck!
The angle which you see the trees is constantly changing because you are moving and the trees are not.

Examples of centripetal acceleration include a car moving around a curve, a spinning top, or a satellite orbiting around Earth. These objects experience centripetal acceleration because their velocity is constantly changing direction towards the center of the circular path they follow.
it means that we are constantly moving.
Hyperextension is the movement that allows you to gaze at the ceiling.
tectonic plates...... duhh
Not if you are moving you can not i dont know why but you cant
