its frame of reference
To determine velocity, you need to know the object's speed (how fast it is moving), the direction in which it is moving (velocity is a vector quantity with magnitude and direction), and the reference point or frame of reference from which the velocity is being measured.
A fast-moving stream is called a river or a torrent.
A speedometer is an instrument used to determine if something is in motion by measuring its speed or velocity. The speedometer indicates how fast an object is moving in relation to a fixed point or reference frame.
Air moving very fast is typically referred to as "wind."
Temperature measures how fast air particles are moving. Higher temperatures mean faster-moving particles, while lower temperatures mean slower-moving particles.
The size and shape of a butterfly's wings, as well as the surrounding environmental conditions such as wind speed, temperature, and air density, play a significant role in determining how fast a butterfly can move. Additionally, the butterfly's metabolic rate and energy levels can also impact its speed.
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
One factor of course would be how fast the wave is moving.

They can determine how fast the star is moving toward or away from us. The chemical spectral signature is used to determine the Doppler shift of the visible light reaching us. This is then used to calculate how fast we and the star in question are moving toward or away from each other.
moving fast in Japanese is "subayai"
Fast moving stream
To determine velocity, you need to know the object's speed (how fast it is moving), the direction in which it is moving (velocity is a vector quantity with magnitude and direction), and the reference point or frame of reference from which the velocity is being measured.
How fast molecules are moving. If they are moving fast its hot, but if they are moving slow it is cold
Gas has fast moving particles.
Fast moving electrons are equivalent to beta radiation.
