difference b/w velocity vector or acceleration vector.
velocity is the rate of the change in the position with respect to time (dx/dt)

Other answers:

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.
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)
|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
