Question

$\mathbb{ \ \ Q\ U\ E\ S\ T\ I\ O\ N\: \: }$
What is the derivation of Kinetic Energy ? ​

Answer 1

Let,

• m=mass of a body at rest
• F=force applied on the body
• s=displacement in the direction of force
• v=final velocity of the body

As,

• v²=u²+2as
• v²=0²+2as
• v²=2as
• s=v²/2a

Then,

• Work=fs
• W=F×S
• W=ma×v²/2a
• W= mv²/
• K = 1/2mv²

Hope this helps you ☺️
