Question

which factor will have a greater effect on the kinetic energy of an object, doubling its mass or velocity?​

Answer 1

Answer:

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.

Answer 2

Answer:

Velocity will have greater effect on kinetic energy as we are squaring the velocity.

As,

K.E = (m x v^2)/2

doubling it's mass as m= 2?

K.E = m x v^2

doubling it velocity as v=2v

K.E = m x (2v)^2

= 4mv^2

hence kinetic energy is increased 4 times by doubling the velocity.
