Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). To keep matters simple, we will focus upon translational kinetic energy. The amount of translational kinetic energy (from here on, the phrase kinetic energy will refer to translational kinetic energy) that an object has depends upon two variables: the mass (m) of the object and the speed (v) of the object. The following equation is used to represent the kinetic energy (KE) of an object.
KE = 0.5 • m • v2
where m = mass of object
v = speed of object
KE = 0.5 • m • v2
where m = mass of object
v = speed of object

Kinetic energy is given by the formula :-
K.E = 1/2(mv^2)
Where “v” refers to velocity; Here speed.
From the equation we get kinetic energy is directly proportional to the square of velocity .
Hence if speed/velocity increases by a factor of 3 , the kinetic energy will increase by a factor of 9.
