## Ruchi. 3 years ago how will you find the average velocity between two points on the displacement time graph?

0)Pick two points on the graph. 1)Find the difference in time between the two points. 2) Find the difference in displacement between the same two points. 3) (Difference in displacement) divided by (difference in time) is the average Speed . You can't tell anything about velocity from the graph except its magnitude, because the graph displays no information regarding the direction of motion.

can u draw it.

5. Ruchi.

bt the formula of avg.vel=change in position /time interval

6. hba

Yeah And I have Done It according to this formula

7. Ruchi.

bt on quest any data is nt given

8. hba

I just gave an example :)

9. Ruchi.

without any data hw can u solve it

10. hba

Ok Give Me Data I will Show it To u

11. Ruchi.

i'm telling without data hw can u solve it. i hav no data

12. hba

Oh So You Want To represent It without data

13. Ruchi.

yes

hlp me out

Well I have already helped you out

Delta r=speedup; Delta t=timeup.

20. problem

assume the displacement as a function of time to be D(t),now you are asked to find out the average velocity between any two points pick the points to be T1 and T2 they are nothing but time at two instant ,now average velocity of a body OVER A TIME INTERVAL is the change in position of the body in that TIME INTERVAL divided by the DIFFERENCE IN TIME INTERVAL ,you'll have to understand that change in position is nothing but D(T1)-D(T2) where D(T1) and D(T2) REPRESENT INSTANTANEOUS position of the particle at time T1 and T2 respectively
