Question

what will be effect on kinetic energy of a body if its velocity becomes half?​

Answer 1

$\huge\boxed{\fcolorbox{orange}{pink}{❥ ᴀɴsᴡᴇʀ}}$

If velocity is doubled, Kinetic Energy increases by 4 times. Kinetic energy of a body is the energy possessed by it, by virtue of its motion, i.e. if the body is moving it will always have kinetic energy.

Answer 2

Answer:

If speed of the body is halved, its kinetic energyis reduced by a factor of 4.

Explanation:

If speed of the body is halved, its kinetic energyis reduced by a factor of 4.
