People are used to a push on something changing where the something is.In fact, though, a push changes the velocity of that something, not where it is.The velocity changes where it is at a later time.In a helicopter rotor, the later time that's noticed is 90 degrees later.It's one of the places in real life where the difference matters.Gyroscopes in general share that.

The velocity changes where it is at a later time.
In a helicopter rotor, the later time that's noticed is 90 degrees later.
It's one of the places in real life where the difference matters.
