Question

what will cause greater change in kinetic energy of a body changing its mass on changing its velocity

Answer 1

changing in velocity because
kinetic energy = 1/2mv^2
The velocity is squared so it will cause greater change than mass.

Answer 2

A change in velocity causes a greater change in a body's kinetic energy.

• A body's kinetic energy is equal to half of its mass multiplied by the square of its velocity.
• As a result, kinetic energy is exactly proportional to mass and square of velocity.
• This suggests that there is a direct link between Kinetic energy and body mass, as well as a parabolic relationship between Kinetic energy and body velocity.
• As a result, a change in velocity has a greater effect on the change in kinetic energy than a change in body mass.
