Solving for Time

he just spent almost 10 minutes explaining 720/3. that's a great teacher

Much more directly, but less poetically, the Latin word for distance is spatium. For this simple reason, we will use s0 (s nought) for the initial location on a path, s for the location on the path any time after that, and Δs (delta s) for the space traversed going from one location to the other -- the distance

I think that 'S' could stand for 'Shift' which is somewhat synonymous with direction.

you are my hero <3

Why they are so fking easys???????

@MyYummycookie Haha I guess. But the physics is sort of basic, nothing super tough or anything! It's just hard for me to grasp the topic right now. Haha

8th grade. Is that possible? I thought it was only for 11th and 12th graders.

It's the same with me.. except I think I'm not the only one who does average.. :P Pushing through though.. (I'm in 8th grade and I'm taking physics)

I agree, and it certainly makes sense when you already understand it, but if you're learning it for the first time and following his directions, you would get the incorrect direction.

The last few seconds of the video doesn't make sense the way he explained it. If we assume + is east and - is west, then if the problem were west, we'd have a negative in the numerator and a negative in the denominator, so it would produce a positive answer (east), when it should still be west.
