Question

Kinetic energy of a body is increased most by doubling its

• A. Mass
• B. Density
• C. Weight
• D. Speed

Answer 1

The correct option is D Speed

So K.E $\alpha$ $v^2$. If we increase velocity, then Kinetic Energy would increase the most.

K.E $\alpha$ m. If we increase the mass, there would be increase in K.E, but as much as compared to the increase in velocity
