after studying in brief about energy now
let's discuss various forms of energy so
in actual there are various forms of
energy like kinetic energy the potential
energy chemical energy heat energy life
energy electrical energy and so on but
in this lecture we are going to study
about only the kinetic energy and the
potential energy now let's start with
the first topic that is kinetic energy
before proceeding further now let's
first revise what is water coming up on
italki gb3
object / we forced legate hence the most
condition may go up jecht a considerable
distance are we move cars ahead in the
direction of applied force and in that
condition we say that work is done the
work done hunk up consider kata here
when there is movement of the object and
this movement is only possible when some
force is applied and some displacement
occurs for example the rotating wheel
the moving cause the blowing wind the
flowing water the fast moving village
extra so these are all the examples of
moving objects that perform some work
hamburger me ask a question put up
karoon cage of window t hair move in
turbine cage ooh blade so there one
could rotate karpati hair
apart from that water Jewett I have a
water turbine may whose core rotate Kurt
I just electricity generate or D hey
Jubilate OT hedge a high velocity soggy
move curly hair the wood target who
striker Patti hey so my question for you
is that these moving objects how are
they managing to accomplish their task

nakum Calipari hey
oh it's energy go ham bowling a kinetic
energy this combat lab a managed to Navy
moving objects keypad key in that case
the energy possessed by them is called
kinetic energy so now let's define what
is this kinetic energy the kinetic
energy is the energy possessed by the
body by virtue of its motion agar Mesa
kinetic energy co work done Cassatt
compare kuru the definition de cacao je
was condition may weaken define kinetic
energy as the kinetic energy of the
moving body with certain velocity let's
say V is equals to the work done on the
body to attain that velocity that is
small V but of a very moving objects key
kinetic energy hair whose condition may
both nihongi jitna whose body Perham
conquering a whose velocity co-main tain
car Nikoli but love kinetic energy of
the moving object is equals to the work
done by the moving object to you thought
our basic fundamentals of kinetic energy
it's comic lab kawaki agar quick body
shall teach lt's rook j those condition
may use curve work done gouget i that is
equals to 0 or kinetic energy Piaget
eggie kinetic energy also becomes 0 so
whenever the system come at the position
of rest in that condition the kinetic
energy of the system becomes zero now
let's see the formula of kinetic energy
suppose there is a ball of mass M or a
volcko point a Perham near okawa here
the ball is at rest his condition makes
initial velocity cow je that is zero
Jessie a miss panic for supply curtain
the ball start moving all yay a point
beeper Praja gauge is per after k
hominis give velocity record kid I just
velocity and it is represented by small
V now the distance traveled by the ball
to cover two points a and B is given by
s as the velocity is continuously
increasing the acceleration KO Jagga it
is represented by small 1/2 is born a
distance s cover Kia whose condition may
is come MATLAB a couch cam Kia the body
has done some work of work a formula
kata force into distance Vercoe home
capital w representing a force KO
capital FC representing a or distance
kohung sa represent cutting gauge we
already studied that work done on the
object is equals to kinetic energy
possessed by the object those condition
made W is also equals to kinetic energy
so very formally may come F into s KO
kinetic energy k equal car dengue now
let's mark it as equation number one
from the Newton's second law of motion
it is given by F is equals to M into a
put this value of F in equation number
one to opt equation KO jayegi it will
become that kind take energy is equals
to M into a into S is question number
two mark Ellijay now from the Newton's
third equation of motion which was v
square minus u square is equals to two a
s now rearranging the equation for the
value of s those condition may
application KO j yi v square minus u
square upon 2 of a put this value of s
in equation number 2 doha mu / calculate
car - Cahan a bob java value put cutting
a two-act equation number 2 k oj e that
can take energy is equals to m into a
into v square minus u square upon 2 of a
a a cancel o Jagga numerator denominator
may a kinetic energy kappa formula camel
jaga m into in Blackgate v square minus
u square upon 2 Kamaraju example a of
america mention keyattr that initial
velocity of the ball is 0-2
it's condition Macau jaga's 0ho jaga a
very valued how can a put Karenga to
kinetic energy formula cuyahoga half MV
square so this is the formula for
kinetic energy where m represents the
mass of the object and V represents the
final velocity of the object Kahuna's
firmly secured conclude gr the first
point is that the kinetic energy is
directly proportional to mass Tusker

here that kinetic energy is directly
proportional to v square but love
