Question

If the speed of the body is halved how does it effect the kinetic energy

Answer 1

here is ur answer ☢️☢️

if the speed is halved then its kinetic energy becomes 1 / 4 th of its original value .

as we know

K.E = 1/2 m v ^2

which means that K = v ^2 , directly proportional to the square of speed .

let us take an example :

K.E = 4 J

V ( speed ) = 16 m / s

if reduced then ,

4 / 2 = 16 / 4

2 J = 4 m / s

hope it helps u ❤❤
