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]
