Question

what is the kinetic energy of an object?. write formula of kinetic energy.

Answer 1

The energy possessed by a body by virtue of its motion is known as kinetic energy.

     ⇒   A moving car is an example of kinetic energy.

K.E. = $\frac{1}{2}$ x mv²

Here, "m" is the mass of the body and "v" is the velocity.

Answer 2

Kinetic Energy is the energy possesed by virtue of motion of a body.
its simplest formulae is 1/2mv^2
where m is mass of body
v is velocity of body
