Velocity is the time rate of change of displacement of an object. Velocity is the distance travelled in unit time in a stated direction. It is a vector quantity since it gives us both magnitude and direction.
Speed of sound has no effect on the particle velocity. Call velocity of sound better speed of sound. Call sound velocity better particle velocity. Velocity of sound is not sound velocity.
Darkness is simply the absence of light. It doesn't make much sense to talk about the "velocity of darkness".
Velocity of light means that light doesn't go instantly from one place to another. If...
Sort of. It is not necessarily highest velocity in general, but it is the highest velocity a certain object can travel. Lets say you drop a penny of of the Empire State Building. When the penny...
Velocity is the measure of increasing and decreasing speed. For example... on a velocity graph, if the object being measured is gradually getting faster the line will go up. If it is getting slower,...
