Answer 1

$<b>●•••••••☆Hello User☆•••••••● 《《Here is your answer》》 <hr size = 3 width = 300 color = #000000 ><font color = #000000> ‍‌‌‌ The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. This change in energy comes from a force that causes an object to move a certain distance. So in order for work to be done on an object, a force must move that object.  </font> <hr size = 3 width = 300 color = #000000 > ●•••••••☆Brainly Star☆•••••••●</b> <b>॥ॐ 卐 ☪ ✝ ॥</b>$

Answer 2

Q- What do you mean by Work Energy Theorem?

A- Work Energy Theorem states that the work done by the body is equal to the change in its kinetic energy.

W = ∆K

PROOF (:

Let there's a body of mass m , moving with a velocity u. It acquires a velocity v after an application of force F and produces a displacement S.

W = F * S__(1) equation

But v^2 = u^2 + 2as

(v^2 - u^2)/2 = s

Putting this value of S in equation (1)

W = ma * ( v^2 - u^2)/2a

W = 1/2 mv^2 - 1/2 mu^2

W = ∆K

Hence Proved !!
