## Ruchi. 3 years ago plz hlp me out :"(

1. Ruchi.

difference b/w velocity vector or acceleration vector.

3. Coolsector

velocity is the rate of the change in the position with respect to time (dx/dt)

4. Coolsector

its magnitude is speed but as a vector it also has a direction

5. Coolsector

acceleration is the rate of the change in the velocity with respect to time (dv/dt or d^2x/dt^2)

6. Ruchi.

@Coolsector

7. Ruchi.

how will u find ag. vel b/w 2 point on d displacement time graph?

8. Ruchi.

can u draw it

9. Ruchi.

the graph

10. Coolsector

|dw:1348397838962:dw|

11. Ruchi.

r u sure its true.

12. Coolsector

yes.. this is how you find the average velocity

13. Ruchi.

i 'm telling abt next question

14. Coolsector

?

15. Ruchi.

i;m telling that hw will u....abt this question

16. Ruchi.

my question hw will u find d avg.vel b/w 2 point on d displacement time graph.

17. Coolsector

by calculating the slope between the two points if the coordinates of point 1 are (t1,x1) and point two (t2,x2) then the average velocity is (x2-x1)/(t2-t1)

18. Coolsector

|dw:1348398831356:dw|

19. Ruchi.

next question shows the expression of relative velocity.

20. Coolsector

relative with respect to..?

21. Ruchi.

show the expression

22. Ruchi.

@satellite73

23. Ruchi.

@Coolsector hlpme out

24. Coolsector

vba = vb - va

25. Coolsector

this is b relative to a

26. Coolsector

and those are vectors..

27. Ruchi.

@Coolsector

28. Coolsector

??

29. Coolsector

relative velocity -> body b relative to body a is given by the vector equation : vba = vb - va

30. Ruchi.

draw vel time graph 4 a particle moving with non-uniform acceleration

31. Coolsector

|dw:1348399535112:dw|

32. Coolsector

for example .. (anything that is not a straight line\linear)

33. Ruchi.

position of particle when acc is maximum bt v=0

34. Ruchi.

@Coolsector

35. Ruchi.

hlp me out

36. Coolsector

graph of position given v=0 at t =0 but has acceleration ?

37. Ruchi.

write the position nt graph

38. Ruchi.

@Coolsector

39. Coolsector

i dont understand what you need

40. Ruchi.

ques;write the postion of a particle , when its acc is max , bt its velocity beccomes zero

41. Coolsector

|dw:1348400395649:dw|

42. Coolsector

like parabola

43. Ruchi.

the graph will nt touch the last line in mean x-plane

44. Coolsector

what ?

45. Ruchi.

r u in habit of saying what|dw:1348404246084:dw|

46. Ruchi.

@Coolsector

47. Coolsector

it may touch .. you can draw infinite graphs describing what you asked for i just gave an example

48. Ruchi.

don't give exampler i 'm confusing
