$K=\dfrac{1}{2}mv^2,$ where $K$ is kinetic energy, $M$ is mass, and $v$ is velocity

Let the kinetic energy be $K$, the mass be $m$, and the velocity be $v$. Kinetic energy is one-half the product of the mass and the square of the velocity. The mathematical equation is $K=\dfrac{1}{2}\cdot m \cdot v^2=\dfrac{1}{2}mv^2$
