Question

Kinetic energy of a body depends upon its:

• A. mass
• B. velocity
• C. density
• D. both A and B

Answer 1

The correct option is D both A and B

Kinetic energy of the body $K=\frac{1}{2}m{v}^2$

$⟹$ $K\propto m$ and $K\propto v^2$

Thus kinetic energy of a body depends on the mass of the body as well as its velocity.
