African or European swallow?
it = speed over time
No. Circular motion can have constant speed but varying velocity. Constant speed means constant speed in any direction, like a car on cruise control turning a corner. Constant velocity means constant speed in a straight line. If the direction changes, that's considered a change in velocity.
The two words are synonyms. However, in physics there is a more precise definition, which is a change in an object's position in a specified direction with time. So in everyday language we could say the speed of the car is 60 miles per hour, but in physics you'd say its velocity is 60 miles per hour North/South/East/West.
The car undergoes a change in velocity. It accelerates (and does so at a constant rate - if the rate of turn is constant) in the direction of the turn. The speed is constant, but the direction the car is going changes at each instant in time because it is turning. And because it is changing direction, that means its velocity is changing (because velocity is speed plus a direction vector).
A seagull cant carry a coconut!
AnswerAre you suggesting that birds migrate? African or European swallow?
Sparrows do not have the physical capacity to carry a coconut, as it is much too heavy in relation to their body size. Therefore, the average speed of sparrows carrying a coconut is assumed to be zero.
It comes from the word hypothesis.The easiest way to explain it is to use it in a sentence."What is the air speed velocity of a swallow carrying a coconut?""Swallows do not carry coconuts.""Ok well, hypothetically, what would it be if they did carry coconuts?"

Group velocity is the speed at which the envelope of a wave packet propagates, carrying energy and information. Phase velocity is the speed at which the individual wave crests propagate. In some cases, the group velocity can exceed the phase velocity, such as in the case of dispersive media.
The average air speed velocity of an unladen European Swallow is approximately 20.1 miles per hour or 9 meters per second. However, this can vary depending on wind conditions and other factors.
A common House Sparrow can fly around 28 mph.
Speed in a given direction is velocity.
SPEED has the speed only; while VELOCITY has the direction and the speed.
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
