Question

hi guys what do you mean by work energy theorem please describe it here​

Answer 1

$\huge{\fcolorbox{cyan}{pink}{Answer:-}}$

❥It states that change in kinetic energy of a body is equal to work done by body.

$\pink{ \boxed{a - b = w}}$

a-final kinetic energy

b- initial kinetic energy

w- work done

Answer 2

Answer:

work energy theorem states that

If a body moves on a straight line

V U A T

v²= u²+ 2as

v²-u²=2as

m/2 multiplying both the sides

m/2 v²-m/2u²=mas ( ma=F)

1/2 mv²- 1/2mu²=F.s

(k. e) f = (k. e) i = F. s ( f= final and i = initial)

(k. e)f= (k. e)i = work done .

Note : where (k.e)f are known as final kinetic energy and K. e as initial kinetic energy

W =( k) f -(K) I

w = work done by the applied force over distance s

W = F. S

W= F. S cos theta
