This question is about what it means for motion to be relative.
00:05
So we've got a few options.
00:08
So first of all, we've got that it means that it's relative to the motion of earth.
00:22
So this isn't the case because even when things are far from earth and earth isn't really involved in their dynamics at all, we can still describe their motion as being relative.
00:33
So it's not this one.
00:37
B, so we've got that it's relative to the motion of any other object.
00:54
And this isn't really the case because it's not just other objects we're thinking about, but it's kind of imagining, you know, what the difference would be.
01:05
Well, there doesn't have to be an object there for motion to be relative, you know, just relative.
01:12
It doesn't have to be a particular object...
