How does the kinetic energy of a moving body depend on its (i) speed and, (ii) mass?

The kinetic energy of a moving body depends on its speed and mass in the following ways:

(i) Speed = Kinetic energy of a moving body is directly proportional to the square of speed of the moving body. [K.E v2]


(ii) Mass = Kinetic energy of a moving body is directly proportional to the mass of the moving body. [K.E m]
