(TRUE) The statement is True.
The formula for kinetic energy $(KE)$ is given by $KE = \frac{1}{2}mv^2$,where $m$ is the mass of the object and $v$ is its speed (or velocity).
Since the formula requires only the mass $(m)$ and the speed $(v)$ of the object to calculate the kinetic energy,knowing these two values allows us to determine the kinetic energy of the object.
