you disturb them from their resting places by your movement and then you go into terminal velocity. The amount of gravity exerted on said dust particle is less then or equal to the amount of wind resistance or drag. Same concept as parachute only on a much smaller scale.

The dust particle was already floating in the air currents. The light ray merely made it visible to the observer.

the small particles of dust don't float just in the light beam.
The dust particles are everywhere most of the time,
it is just that the light ray highlights them, and you see them.

Small dust particles does not float in the sun rays.They are present but nwe cannot see them.when the sunlight fall on them the become visible and appear as they are floating in sunlight.

Dust particles are always there, they dont just appear in light, the light just makes it easier for you to see the particles.

The air is filled with dust particles most of the time,a beam of light just illuminates them and makes them visible.

theyre already floating even without the light
They float when force is applied, theyre mass is so small, it will take an hour for them to go back to the ground, depends of the height, or its just dust from the outside
