प्रश्न
How does the kinetic energy of a moving body depend on its (i) speed, and (ii) mass?
उत्तर
The kinetic energy of a moving body depends on two factors because:
(i) Kinetic energy of a moving body is directly proportional to the square of the speed of the moving body.
(ii) Kinetic energy of a moving body is directly proportional to the mass of the moving body.
