Question

Which will bring more change in the kinetic energy of a

moving body - doubling the speed or doubling the

mass?​

Answer 1

Answer:

Which has greater effect on the kinetic energy of an object : doubling the mass or doubling the velocity? Kinetic energy is directly proportional to the square of the velocity. Therefore, doubling the velocity has greater effect on the kinetic energy of the object than doubling its mass.
