Question

Kinetic energy of a body is directly proportional to its :

• A. Weight
• B. Speed
• C. Mass
• D. None

Answer 1

The correct option is C Mass

As kinetic energy is given by:
$K.E=\frac{1}{2}m{v}^2$
So, the kinetic energy of a moving body is directly proportional to its mass and the square of its velocity.
So, option C, D is correct.
