difference b/w velocity vector or acceleration vector.

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

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

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

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

can u draw it

the graph

|dw:1348397838962:dw|

r u sure its true.

yes.. this is how you find the average velocity

i 'm telling abt next question

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

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

|dw:1348398831356:dw|

next question shows the expression of relative velocity.

relative with respect to..?

show the expression

@Coolsector hlpme out

vba = vb - va

this is b relative to a

and those are vectors..

??

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

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

|dw:1348399535112:dw|

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

position of particle when acc is maximum bt v=0

hlp me out

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

write the position nt graph

i dont understand what you need

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

|dw:1348400395649:dw|

like parabola

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

what ?

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

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

don't give exampler i 'm confusing
