physics help!!

what does an ‘i’ with a ‘>’ at the top mean? also what does a ‘J’ with a ‘>’ mean? does it have something to do with direction?

<p>A > means that it’s a vector. Since you can’t really write bold (as most books choose to notate vectors), you have to use the > on top. (I think so, but don’t quote me on this).</p>

<p>Shouldn’t that be a “^” on top? If it’s “i” with a “^” on top (</p>

<p>i agree with jared’s analysis… my physics teacher enjoys saying “x-hat” and “y-hat” and I have finally figured out what he means and when to include it in my homework problems.</p>

<p>I dont know about the x-hat y-hat thing, but i’m pretty sure vectors have lines on top, not >.</p>

<p>Yeah, jared is right. A vector would have a small arrow on the top.</p>

<p>There are a lot of ways to denote that it’s a vector. I can’t imagine i and j being anything but vectors in physics (it would be VERY odd for someone to make the variables be called i and j).</p>
