Jan 22, 2021 at 10:05 comment added DakkVader @James0987 Definetly. Or since your material seems to go through this now, I'd say pretty soon. If you're happy with the answer you can mark it as solved. Or wait until a bettero ne comes along.
Jan 22, 2021 at 10:01 comment added James0987 So basically, I will understand it when i learn about vectors in math?
Jan 22, 2021 at 9:59 comment added DakkVader Depends on the notation you use. Either it can be that you move $-2\hat{x}$ or you move $2\left(\hat{-x}\right)$. (If x-direction is the direction in which you move). $\hat{x}$ represents a unit vector in a direction. I.e it is a vector in direction $x$ of length 1.
Jan 22, 2021 at 9:58 comment added James0987 Ok, thank you! One question more. When will the velocity be positive or negative? If i move up will it be negative and vice versa?

Jan 22, 2021 at 9:55 comment added DakkVader The delta is not crucial, therfore it was probably omitted. It would still represent the distance. I guess here $S = S_2 - S_2$. Or anything that symbolises a distance travelled.It could also be a typo. We will never know. But I'm 100% certain that the equations are depicting speed and velocity, i.e presenting that they are two different things.
Jan 22, 2021 at 9:54 comment added James0987 I mean in my book it doesn't say Delta s. I don't know why?
