When an object completes a circumference, that's the same as just saying it started here.
00:06
It went in circular motion and ended up right back where it started.
00:10
That's completing a circumference.
00:12
So that sort of gives away one of the true statements.
00:15
It's displacement, which we usually denote is delta x, but in this case, i think we might want to call it delta theta.
00:23
At this point in time is zero.
00:24
And that's true because it went back to right where it started.
00:27
So the displacement is zero.
00:28
The total distance traveled isn't zero, but that's not what it's asking.
00:32
It's asking how far displaced from its original location is it, and that's zero.
00:38
The next statement is that its average velocity, or its average speed, sorry.
00:43
So the magnitude of velocity with an average sign over it, saying that that is zero during its motion...
