Question

-------------

Answer 1

1- displacement
2- acceleration
3- velocity

Am I right?

Answer 2

do you know what those things are (displacement, velocity, acceleration and vector)?

Answer 3

well, i can see by your answer you probably don't.

Answer 4

Can you please elaborate then?

Answer 5

i do know what is a vector

Answer 6

a displacement vector points to where the object is at a certain time.

a velocity vector points to which direction it is moving at a certain time.

an acceleration vector points to the general direction you will be going shortly, or the direction in which you want to change your velocity.

Answer 7

3 = displacement
2 = acceleration
1 = velocity

right?

Answer 8

does that make sense?

Answer 9

Well the vector 3 is pointing towards graph whereas vector 1 is telling where its heading

Answer 10

and do you see vector 2 is pointing in the direction where the particle move soon after?

Answer 11

exactly, so acceleration

Answer 12

am I right? :P

Answer 13

yep

Answer 14

wow, that was easy, thanks man :)

Answer 15

Last question: do we have any information about the speed?

Ans:
No, since no value at x or y? is that correct?

Answer 16

you really don't... you could compute the length of the vector (if you had coordinates) but without the units you really couldn't say.

Answer 17

what was easy?

Answer 18

Exactly, thanks man :)

Answer 19

you're welcome!

Answer 20

Yep, quite easy :)
