their average speed is greater than their average velocity.
It pretty much started when cavemen painted on walls. But if you are talking about contemporary art, it started around the Renaissance when artists broke away from their low societal positions in only painting church-commissioned bible scenes and began to express their individual emotions rather than just illustrating The Bible.

The average IQ of a fourth grader is around 90-110, but honey, IQ tests aren't everything. Some kids are book smart, some are street smart, and some are just plain old charming. So don't stress too much about a number that doesn't define your worth. Just keep being your fabulous self!

The NBA lottery began in 1985 but did not reach its present style until 1987. Prior to 1985, a coin flip determined the draft pick overall.
a key.
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
The moon's average velocity around Earth is about 2,288 miles per hour.
Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.
His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)
His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
The average velocity of a unicycle going around semicircles would be zero if it starts and ends at the same point, since the displacement is zero. If it starts and ends at different points, the average velocity would depend on the total distance traveled and the time taken to complete the semicircles.
His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)
No, the average velocity is not zero. Average velocity is the total displacement divided by the total time taken. For one lap around the track, the athlete ends up back at the starting line, so the total displacement is not zero.
The average velocity of atoms in a monatomic gas can be calculated using the root-mean-square speed formula. For neon at 288 K, the average velocity would be around 494 m/s.
The velocity sensor should be placed at approximately 40-60% of the total water depth, so in this case, it should be placed at around 5-7.5 meters from the surface to estimate the stream's average velocity accurately. Placing it in this range helps account for variations in velocity across the vertical profile of the stream.
The average overhand throw velocity for Division 1 softball players is around 60-70 miles per hour. This velocity can vary depending on the position of the player and their level of experience and training.
