Question

which would have a greater effect on the kinetic energy of an object: doubling the mass or doubling the velocity?

Answer 1

Hello mate

If the velocity of a body is doubled, its kinetic energy becomes four times and if the velocity of a body is halved, then its kinetic energy becomes one- fourth.. It is obivious that doubling the velocity has a greater effect on the kinetic energy of a body than doubling its mass. 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.Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.
