Question

Can any one teach me all the graphs in motion in a straight line chapter , including the way the questions will be asked from the graphs and extras , please ?

Answer 1

@sauravshakya

Answer 2

what do u want to know....

Answer 3

everything .. the position-time graph at rest , uniform motion , non uniform motion
dist-time graph .. almost every graphs !

Answer 4

OK now I am free......

Answer 5

:)

Answer 6

do u know what a uniform motion means

Answer 7

yeah motion in a straight line ?

Answer 8

covering equal distance in equal intervals of time .

Answer 9

I dont think so.....

Answer 10

then ?

Answer 11

yeah the second one is correct

Answer 12

so first one is not right ?

Answer 13

yeah......

Answer 14

okay !

Answer 15

I think u only need linear uniform motion......I mean uniform motion in a straight line

Answer 16

right?

Answer 17

yeah !

Answer 18

so.... in a linear uniform motion.... accleration is 0 so we have only one formula....
and that is s=ut

Answer 19

got it?

Answer 20

okay !

Answer 21

Now, lets talk about non uniform linear motion.....

Answer 22

okay ..

Answer 23

here the velocity of the body changes so we will have accleration.. right?

Answer 24

how ?

Answer 25

in a non uniform linear motion . velocity changes .... right?

Answer 26

yeah !

Answer 27

so...... if velocity changes there is always accleration right?

Answer 28

yeah okay , got it :)

Answer 29

So we have some equation of motions..... to descibe non uniform linear motion

Answer 30

I think u know them........

Answer 31

right?

Answer 32

v = u+at
s = ut + 1/2at^2
v^2 - u^2 = 2as
these ones ?

Answer 33

yep.......

Answer 34

okay !

Answer 35

now, while using these formula u must be very careful

Answer 36

because velocity, and accleration are vector quantites

Answer 37

so their sign differs with respect to the direction

Answer 38

so what's the problem ?

Answer 39

oh !

Answer 40

got it?

Answer 41

okay .. like ?

Answer 42

if u take
