Question

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

the velocity?​

Answer 1

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.

Answer 2

Answer:

Doubling the velocity will be more effective on kinetic energy of a body

as Kinetic energy is proportional to Square of velocity of that object .

[ K.E. ≈ V² ]
