Question

acceleration, velocity, speed i will provide some images help me .. :) :)

Answer 1

i need explanation from 29 to 37 plz help me i need it .. :)

Answer 2

these are derivations for the equations of motion...

Answer 3

Everything is already explained.. they are just derivations... what help do you need?

Answer 4

how the function was derived this is my 1st experience .. :

Answer 5

i am new in physics .. but i am 23 for interest i am learning physics... so confused..

Answer 6

these are equation of motion along a straight line, and its derivation

Answer 7

okay. jatinbansalhot define acceleration

Answer 8

@adnanSultan but there is no lim in there ..

Answer 9

accel = change in velocity / total time taken

Answer 10

yes. we shall take the final velocity to be "v" and initial velocity to be "u" and the time taken to reach velocity "v" to be "t".
are we clear?

Answer 11

@chand yah ... i got u ... upto now . :)

Answer 12

chand in which class do u read, i send definition on your standid

Answer 13

lim are not necessarily

Answer 14

@adnanSultan really ? i thought it is necessary for finding out derivative..

Answer 15

@adnanSultan i'm in my 12th. @jatinbansalhot according to the definition of acceleration i.e rate of change of velocity,
\[a= v-u /t\]

Answer 16

at= v-u

v = u + at

Answer 17

@chand yah chand i am following u .. this too i understood ..

Answer 18

@chand why we are interested in at

Answer 19

the time rate of change of velocity is called acceleration. that is best definition for you chand.

Answer 20

at is acceleration multiplied by time. when we transpose "t" from LHS to RHS, that is the equation we get.

Answer 21

are we clear?

Answer 22

every data is given in your figure only apply it

Answer 23

yah .. but why we are finding out at ... what do we need that :)

Answer 24

All the data is given to solve the equations of motion..........

Answer 25

we are just solving the equation to find out the final velocity. that's it.

Answer 26

ohhh.... to find that .. ohhhhhhhhhhhhhhhhhh

Answer 27

or see it this way : we nee do find "at" to find velocity as a function of time.

Answer 28

@chand now i got everything this was the main problem to understand :) thanks chand .. really thanks :) :)

Answer 29

no problem.

Answer 30

are you good with the second equation of motion?

Answer 31

Yes.
