If the velocity of the moving body is doubled (m remaining constant), then the kinetic energy of the body increases by how many times?1. Increases by 4 times2. Increases by 6 times3. Becomes one-fourth4. Remains constant

Answer» Correct Answer - Option 1 : Increases by 4 times

The correct answer is Increases by 4 times.

  • The kinetic energy of an object is defined as the energy that it possesses due to its motion.

  • An object that has motion possesses kinetic energy.
  • The amount of kinetic energy that an object has depends upon two variables-
    • the mass (m) of the object 
    • the speed (v) of the object
  • If the velocity of the moving body is doubled, then the kinetic energy becomes 4 times because the kinetic energy of a body is directly proportional to the square of its velocity when the mass of the body is kept constant.
