Question

define kinetic energy and also derive K.E.=1/2 mv2​

Answer 1

ANSWER -

Energy posses by a body by virtue of its motion is referred to as 'Kinetic Energy'". FORMULA. K.E. = 1/2 mv2. Kinetic energy depends upon the mass and velocity of body. If velocity is zero then K.E. of body will also be zero.

Answer 2

Answer:

Kinetic energy is the energy possessed by an object due to its motion.

Explanation:

Kinetic energy= F × s

F =m×a.

s=v²-u²/2a.

so

K.E= ma×v²/2a ( let the initial velocity be 0)

=mv²/2

=1/2mv²

Hence derived.
