sorry, did middle schoolers get taught the earth spins twice a day? 3 times? 17 times? or maybe they get taught that the time taken for it to spin once is actually called the sidereal day and not the synodic day?

if you want to measure how fast things spin, use angular velocity. your car engine goes at several thousand rpm, not several thousand kilometers per hour. if you were standing at the poles, you would have zero linear velocity. does this mean the earth doesn't spin?

ok maybe you were talking about the time the earth takes to go around the sun. yes that takes a year.
