Question

Which is having more effect on the kinetic energy. Either increase of velocity or increase of mass of the object? [2 MARKS]

Answer 1

Each point: 1 Mark

1. We know, kinetic energy = $\frac{1}{2}m{v}^2$

2. We see that kinetic energy is proportional to the square of the velocity while it is just linearly proportional to the mass. So, we can say that velocity having more effect on the kinetic energy compare to mass.
